A Community Health Nursing Perspective
Table of Contents
Introduction to Cancer as an NCD
Cancer stands as one of the leading non-communicable diseases (NCDs) globally, representing a significant burden on healthcare systems and communities. Community health nurses play a pivotal role in cancer screening, early detection, prevention education, and continuity of care within the community setting.
Community health nurse conducting cancer screening and education
This comprehensive guide focuses on three prevalent cancers: cervical, breast, and oral cancers. Each section provides in-depth information on epidemiology, risk factors, prevention strategies, screening protocols, diagnostic approaches, and management guidelines from a community health nursing perspective.
Key Fact: According to the World Health Organization (WHO), cancer is the second leading cause of death globally, accounting for an estimated 9.6 million deaths in 2018. However, between 30-50% of all cancers are preventable through effective cancer screening and health promotion strategies.
Cervical Cancer
Epidemiology
Cervical cancer represents the fourth most common cancer among women globally, with an estimated 570,000 new cases and 311,000 deaths worldwide annually. The burden is disproportionately high in low- and middle-income countries where access to cancer screening services is limited.
Global Distribution of Cervical Cancer
| Region | Incidence Rate | Mortality Rate | 5-Year Survival |
|---|---|---|---|
| Sub-Saharan Africa | High (>40 per 100,000) | High (>20 per 100,000) | Below 50% |
| South-East Asia | Moderate-High (15-30 per 100,000) | Moderate-High (8-15 per 100,000) | 50-65% |
| Latin America | Moderate (10-20 per 100,000) | Moderate (5-12 per 100,000) | 60-70% |
| North America/Western Europe | Low (6-10 per 100,000) | Low (2-5 per 100,000) | Above 70% |

Risk Factors
Cervical cancer is primarily caused by persistent infection with high-risk types of human papillomavirus (HPV), particularly types 16 and 18. Community health nurses should educate populations about the following risk factors:
Primary Risk Factors
- Persistent HPV infection (types 16, 18, 31, 33, 45, 52, 58)
- Early sexual debut (before age 17)
- Multiple sexual partners
- History of sexually transmitted infections
- Smoking (direct and secondhand)
- Long-term use of oral contraceptives (>5 years)
- Weakened immune system (HIV/AIDS, immunosuppressive medications)
Contributing Factors
- High parity (giving birth to many children)
- Young age at first full-term pregnancy
- Low socioeconomic status
- Poor nutrition (low in fruits and vegetables)
- Family history of cervical cancer
- Lack of access to regular cancer screening
- Diethylstilbestrol (DES) exposure in utero
Mnemonic: “CERVICAL”
C – Cigarettes (smoking)
E – Early sexual activity
R – Reproductive history (high parity)
V – Viral infection (HPV)
I – Immune system compromise
C – Contraceptives (long-term oral)
A – Abnormal Pap history
L – Low socioeconomic status/Limited access to healthcare
Prevention
Cervical cancer is highly preventable through comprehensive prevention strategies. Community health nurses should focus on the following approaches:
Primary Prevention
- HPV Vaccination: Recommended for girls and boys aged 9-14 years (ideally before sexual debut)
- Safe sexual practices: Consistent condom use, limiting sexual partners
- Smoking cessation: Community-based tobacco control programs
- Health education: Age-appropriate comprehensive sexual education
Secondary Prevention
- Regular cancer screening: Pap smears, HPV testing, visual inspection with acetic acid (VIA)
- Treatment of precancerous lesions: Cryotherapy, LEEP, conization
- Follow-up management: Ensuring adherence to screening guidelines
Community Nurse Tip: When organizing community cancer screening programs, pair them with educational sessions. Providing information on HPV vaccination and cervical cancer prevention alongside screening services can significantly increase participation rates and improve health outcomes.
Screening
Early detection through regular cancer screening is crucial for cervical cancer prevention and control. Community health nurses should be familiar with the following screening approaches:
Cervical Cancer Screening Methods
| Method | Description | Recommended Frequency | Advantages | Limitations |
|---|---|---|---|---|
| Pap Smear | Cytological examination of cervical cells | Every 3 years (21-65 years) | Well-established, widely available | Moderate sensitivity, requires laboratory infrastructure |
| HPV DNA Testing | Detection of high-risk HPV types | Every 5 years (30-65 years) | High sensitivity, objective results | Higher cost, requires specialized equipment |
| Co-testing (Pap + HPV) | Combined testing approach | Every 5 years (30-65 years) | Highest sensitivity | Most expensive option, potential overtreatment |
| VIA | Visual inspection with acetic acid | Every 3-5 years (30-50 years) | Low cost, immediate results, suitable for LMIC | Subjective, variable sensitivity, requires training |
WHO-Recommended Cervical Cancer Screening Guidelines
The WHO recommends that each country should implement a cervical cancer screening program based on its resources:
- Low-resource settings: Screen women aged 30-49 years with VIA at least once in a lifetime
- Middle-resource settings: Screen women aged 30-49 years with HPV testing every 5-10 years
- High-resource settings: Screen women aged 25-65 years with HPV testing every 5 years or cytology every 3 years
Signs, Symptoms & Diagnosis
Community health nurses should be knowledgeable about early signs and symptoms of cervical cancer to facilitate prompt referral and diagnosis.
Early Signs and Symptoms
- Abnormal vaginal bleeding (between periods, after intercourse, after menopause)
- Unusual vaginal discharge (may be watery, bloody, or foul-smelling)
- Pelvic pain or pain during intercourse
- Unexplained weight loss
- Fatigue
Late Signs and Symptoms
- Persistent back, leg, or pelvic pain
- Difficulty urinating or defecating
- Blood in urine
- Swelling of one or both legs
- Unexplained anemia
- Kidney failure due to obstructed ureters
Diagnostic Procedures
- Colposcopy: Detailed examination of the cervix using a magnifying instrument
- Biopsy: Collection of tissue samples from suspicious areas for pathological examination
- Endocervical curettage: Scraping of the endocervical canal
- Imaging studies: CT scan, MRI, PET scan for staging and evaluating spread
- Blood tests: Complete blood count, kidney and liver function tests
Important: Early-stage cervical cancer is often asymptomatic. This underscores the critical importance of regular cancer screening even in the absence of symptoms.
Early Management & Referral
Community health nurses play a crucial role in early management and timely referral of suspected cervical cancer cases.
Management and Referral Pathway
1. Abnormal Screening Results
- Provide clear explanation of results to the patient
- Emphasize importance of follow-up
- Schedule referral appointment
2. Referral to Colposcopy Clinic/Gynecologist

|---|---|---|
| Precancerous lesions | LEEP, cryotherapy, conization, laser therapy | Explanation of procedure, follow-up scheduling, addressing concerns |
| Stage I | Surgery (conization, radical hysterectomy), radiation | Pre/post-surgical teaching, wound care education, symptom management |
| Stage II-III | Combined radiation and chemotherapy, surgery | Side effect management education, nutritional guidance, emotional support |
| Stage IV | Chemotherapy, targeted therapy, palliative care | Symptom management, home care coordination, end-of-life discussions |
Breast Cancer
Epidemiology
Breast cancer is the most common cancer among women worldwide and the second leading cause of cancer death in women. In 2020, there were approximately 2.3 million new cases globally and 685,000 deaths. The incidence varies significantly across regions but has been increasing in almost all countries.
Global Breast Cancer Statistics
| Region | Incidence Rate (per 100,000) | Mortality Rate (per 100,000) | 5-Year Survival |
|---|---|---|---|
| North America | 85-90 | 12-14 | 90% |
| Western Europe | 75-85 | 15-17 | 85% |
| Eastern Asia | 25-40 | 6-10 | 82% |
| Sub-Saharan Africa | 30-40 | 15-20 | 40-60% |
Data source: GLOBOCAN and World Health Organization estimates
Key Fact: Although developed countries have higher incidence rates of breast cancer, mortality rates tend to be higher in developing countries due to later stage diagnosis and limited access to treatment. This highlights the critical importance of cancer screening and early detection programs in community health nursing.
Risk Factors
Understanding breast cancer risk factors is essential for targeted cancer screening and prevention strategies in community health nursing. These factors can be categorized as modifiable and non-modifiable:
Non-Modifiable Risk Factors
- Gender: Being female (though males can develop breast cancer too)
- Age: Risk increases with age; majority of cases diagnosed after 50
- Genetic factors: BRCA1, BRCA2 mutations (5-10% of cases)
- Family history: First-degree relatives with breast cancer
- Personal history: Prior breast cancer or certain benign breast conditions
- Dense breast tissue: Higher density on mammogram
- Early menarche/late menopause: Extended estrogen exposure
- Previous chest radiation: Especially before age 30
Modifiable Risk Factors
- Reproductive factors: Nulliparity or first pregnancy after age 30
- Hormone therapy: Combined estrogen-progestin hormone replacement therapy
- Alcohol consumption: Risk increases with amount consumed
- Obesity: Especially after menopause
- Physical inactivity: Sedentary lifestyle
- Smoking: Particularly long-term, heavy smoking
- Diet: High-fat diets with minimal fruits and vegetables
- Environmental exposures: Certain chemicals and radiation
Mnemonic: “BREAST CANCER”
B – BRCA gene mutations
R – Radiation exposure (previous)
E – Estrogen exposure (prolonged)
A – Age (increasing)
S – Sex (female)
T – Tissue density (high)
C – Childlessness or late first pregnancy
A – Alcohol consumption
N – Nulliparity
C – Close relatives with breast cancer
E – Exercise deficiency
R – Reproductive history (late menopause/early menarche)
Prevention
Breast cancer prevention strategies are essential components of community health nursing interventions. They focus on risk reduction through lifestyle modifications and early detection through appropriate cancer screening.
Primary Prevention Strategies
- Physical activity: Regular exercise (150+ minutes moderate activity/week)
- Healthy diet: Rich in fruits, vegetables, whole grains; limit processed foods
- Weight management: Maintaining healthy BMI, especially after menopause
- Limited alcohol: No more than one drink per day for women
- Breastfeeding: When possible, for at least 12 months cumulative
- Avoiding hormone therapy: Or minimizing duration if necessary
- Tobacco avoidance: Not starting or quitting smoking
Chemoprevention for High-Risk Women
For women at high risk, preventive medications may be considered under medical supervision:
- Selective estrogen receptor modulators (SERMs): Tamoxifen, Raloxifene
- Aromatase inhibitors: Exemestane, Anastrozole
- Prophylactic surgery: For BRCA mutation carriers or very high-risk women
Community Nurse Tip: When organizing breast cancer awareness programs in the community, incorporate practical demonstrations of breast self-examination techniques using models. This hands-on approach greatly improves women’s confidence and ability to correctly perform self-examinations at home.
Screening
Breast cancer screening is crucial for early detection and improved outcomes. Community health nurses should be familiar with screening guidelines and modalities to effectively implement and promote cancer screening programs.
Breast Cancer Screening Methods
| Method | Description | Recommended Age/Frequency | Advantages | Limitations |
|---|---|---|---|---|
| Breast Self-Examination (BSE) | Self-inspection and palpation of breasts | Monthly after age 20 | No cost, increases breast awareness | Low sensitivity, may cause anxiety |
| Clinical Breast Examination (CBE) | Examination by healthcare provider | Every 1-3 years (20-39); annually (40+) | Can detect changes missed by imaging | Varies with examiner expertise |
| Mammography | X-ray imaging of breast tissue | Every 1-2 years from age 40-74 | Can detect tumors before palpable | Less effective in dense breasts, false positives |
| Digital Breast Tomosynthesis (3D) | Advanced form of mammography | Same as mammography | Better for dense breasts, fewer false positives | Higher radiation dose, higher cost |
| Ultrasound | Sound wave imaging | Supplemental to mammography | No radiation, good for dense breasts | Operator-dependent, false positives |
| MRI | Magnetic resonance imaging | Annual for high-risk women | Most sensitive method, no radiation | Expensive, low specificity, contraindications |
Breast Self-Examination Technique
Community health nurses should teach the following BSE steps:
- Visual inspection: Stand before a mirror with arms at sides, then raised, looking for changes in contour, swelling, dimpling of skin, or nipple changes
- Lying down examination: Place a pillow under the right shoulder and place right hand behind head. Use left hand to examine right breast in a circular pattern moving from outside to center, including armpit area. Repeat for left breast.
- Shower examination: Raise one arm and use soapy fingers to check each breast and armpit in circular motions
- Nipple check: Gently squeeze each nipple to check for discharge
Screening Recommendations by Risk Level
| Risk Category | Definition | Recommended Screening Protocol |
|---|---|---|
| Average Risk | Women with no specific risk factors | Mammography every 1-2 years starting at age 40-50 (varies by guideline) |
| Moderate Risk | Family history in second-degree relatives, dense breasts, personal history of benign breast disease | Start mammography at 40, consider annual screening |
| High Risk | BRCA mutations, strong family history, previous chest radiation, personal history of breast cancer | Annual mammography + MRI starting at age 30, consider genetic counseling |
Signs, Symptoms & Diagnosis
Community health nurses should educate women about breast cancer signs and symptoms and facilitate early diagnosis when abnormalities are detected.
Common Signs and Symptoms

- Buccal mucosa: Right and left cheek linings
- Gingiva and alveolar ridges: Upper and lower gums
- Tongue:
- Dorsal surface: Have patient stick tongue out
- Lateral borders: Have patient move tongue side to side
- Ventral surface: Have patient touch palate with tongue
- Floor of mouth: Have patient lift tongue to roof of mouth
- Hard and soft palate: Tilt patient’s head back
- Oropharynx: Depress tongue with tongue depressor
Screening Protocol for Community Settings
Target populations for prioritized screening:
- Individuals with tobacco use history (current or former)
- Regular alcohol consumers
- Betel quid/areca nut users
- Those with previous oral cancer or precancerous lesions
- Individuals over 40 years with multiple risk factors
- Patients with unexplained oral symptoms persisting >3 weeks
Recommended screening frequency: Annual examination for high-risk individuals; opportunistic screening during routine health visits for others.
Signs, Symptoms & Diagnosis
Community health nurses should educate community members about the warning signs of oral cancer and facilitate early diagnosis through appropriate referrals.
Early Warning Signs
- Persistent mouth sore that doesn’t heal within 2-3 weeks
- White or red patch on the gums, tongue, tonsil, or mouth lining
- Lump or thickening in the cheek
- Persistent sore throat or feeling that something is caught in the throat
- Difficulty chewing or swallowing
- Difficulty moving the jaw or tongue
- Numbness of the tongue or other area of the mouth
- Swelling of the jaw causing dentures to fit poorly
Advanced Symptoms
- Pain or bleeding in the mouth
- Loosening of teeth
- Voice changes
- Weight loss
- Bad breath not responding to oral hygiene
- Earache (referred pain)
- Enlarged lymph nodes in the neck
- Facial asymmetry
- Progressive limitation in mouth opening (trismus)
Mnemonic: “ALERT” for Oral Cancer Warning Signs
A – Abnormal bleeding or pain in the mouth
L – Lumps or thickening of oral tissues
E – Erosion or sores that don’t heal within 2-3 weeks
R – Red or white patches in the mouth
T – Trouble with swallowing, chewing, speaking, or moving jaw/tongue
Diagnostic Process
- Clinical examination: Thorough head and neck examination including lymph nodes
- Biopsy: Gold standard for diagnosis
- Incisional biopsy: Removal of part of the lesion
- Excisional biopsy: Complete removal of small lesions
- Fine needle aspiration: For neck masses
- Imaging studies: To determine extent and stage
- CT scan: Bone invasion, lymph node involvement
- MRI: Soft tissue invasion, perineural spread
- PET-CT: Metastatic disease detection
- Panoramic radiography: Jaw involvement
- Endoscopy: Nasopharyngolaryngoscopy for oropharyngeal involvement
- Staging assessment: TNM classification (Tumor, Node, Metastasis)
Important: Any oral lesion that persists for more than 2-3 weeks should be referred for professional evaluation, regardless of whether it is painful. Pain is often absent in early oral cancer, contributing to delayed diagnosis.
Early Management & Referral
Community health nurses should be familiar with appropriate referral pathways and supportive care for patients with suspected or diagnosed oral cancer.
Referral Pathway for Suspicious Oral Lesions
1. Initial Detection
- Document appearance, size, location, duration, and associated symptoms

- Unexplained swelling or lump
- Unexplained tooth mobility not associated with periodontal disease
- Unexplained paresthesia or numbness
- Unexplained neck mass
3. Referral Process
- Urgent referral: Within 2 weeks for suspicious lesions
- Routine referral: Within 4 weeks for less suspicious but persistent lesions
- Refer to oral medicine specialist, oral surgeon, ENT specialist, or head and neck oncology center based on local resources
4. Community-Based Support During Treatment
- Nutritional support and guidance
- Oral hygiene maintenance
- Pain management
- Psychological support
- Rehabilitation and speech therapy coordination
- Assistance with smoking/alcohol cessation
Treatment Modalities Overview
| Treatment Type | Description | Community Nurse Role |
|---|---|---|
| Surgery | Primary treatment for most oral cancers; may involve removal of tumor, surrounding tissue, and sometimes lymph nodes | Pre-operative education, post-operative wound care, addressing changes in appearance and function |
| Radiation Therapy | May be primary treatment or adjuvant after surgery | Oral care during radiation, managing xerostomia (dry mouth), mucositis, and skin reactions |
| Chemotherapy | Often combined with radiation for advanced cases | Side effect management, nutrition support, infection prevention |
| Targeted Therapy | Drugs targeting specific cancer cell features | Medication adherence support, specific side effect monitoring |
| Reconstructive Surgery | Restore form and function after tumor removal | Rehabilitation coordination, adaptation strategies for daily activities |
| Supportive Care | Symptom management, nutritional support | Care coordination, caregiver education, accessing community resources |
Community Nurse Tip: Create oral care kits for patients undergoing oral cancer treatment. Include soft toothbrushes, alcohol-free mouthwash, fluoride gel, water-based lip moisturizer, and instructions for gentle oral hygiene. This helps prevent complications like mucositis and dental decay that commonly occur during treatment.
