Aging and Cancer: Risk Factors, Prevention & Screening
Aging and Cancer
Overview
This section covers the relationship between aging and various types of cancer, focusing on risk factors, prevention, and screening guidelines that have not been previously discussed.
Cancer of the Vagina
Risk: Rare; often arises from metastasis.
Chronic Irritation: Women with conditions such as chronic vaginitis or those who wear a pessary should undergo frequent Pap smears due to increased risk.
Clinical Concerns:
Presence of vaginal ulcers or masses should prompt evaluation for malignancy; all masses detected in older women should be considered suspicious and should undergo biopsy.
Signs and Symptoms:
Vaginal ulcers, masses, chronic discharge.
Treatment Options:
Topical chemotherapeutic agents.
Radiation therapy.
Surgical interventions.
Cancer of the Cervix
Risk: Rare but varies by ethnicity:
1. Hispanic women
2. Black women
3. White women
Clinical Manifestations:
Symptoms may include vaginal bleeding and leukorrhea (thick white or yellowish discharge).
Pain is typically absent in early stages.
As the disease advances, complications such as urinary or fecal incontinence and uremia may occur.
Treatment:
Radiation therapy.
Surgical options as necessary.
Cancer of the Endometrium
Risk Factors: Primarily affects older women, with increased incidence linked to:
Late onset of menstrual periods.
Infertility.
Family history of endometrial cancer.
Obesity.
Clinical Manifestations:
Postmenopausal bleeding is a key warning sign.
Treatment Options:
Radiation therapy.
Surgical interventions depending on the case.
Cancer of the Ovaries
Risk: Increased incidence with age, responsible for 5% of malignant diseases in women, yet it remains the leading cause of death from gynecologic cancers.
Clinical Correlate: Symptoms are nonspecific and can often be misinterpreted as gastrointestinal discomfort (gas pain).
Presence of benign tumors is common; a biopsy is necessary to exclude malignancy.
Treatment:
Radiation therapy.
Surgical options to address malignancy.
Breast Cancer
Risk: Second leading cause of cancer death among women.
Risk increases with age; family history is a significant risk factor.
Detection:
Regular breast examinations are critical:
Yearly from ages 40 to 75.
Every 2-3 years after age 75.
Diagnosis and Treatment:
Treatment approaches remain consistent across age groups and are based on the cancer's type and stage.
Treatment Approaches for Older Adult Cancer Patients
Conventional Treatments Include:
Surgery.
Radiation therapy.
Chemotherapy.
Biologic therapy; these are consistent with treatments used in younger adults.
Risks: Older adults face a higher risk of mortality and complications from cancer treatments compared to younger populations.
Age Considerations: Advanced age affects:
Pharmacokinetics: how the body affects a drug.
Pharmacodynamics: how a drug affects the body, especially concerning cytotoxic drugs.
Promotion of Optimum Care
Key Components:
Selection of appropriate treatment facilities.
Availability of clinical trials through the National Cancer Institute (NCI).
Comprehensive post-treatment care post-radiation and chemotherapy, addressing age-related risk increases.
Awareness of common age-related factors that compound risk for various conditions.
Prevention of Complications
Age-Related Issues: Complications often arise from increased risk of:
Malnutrition.
Dehydration.
Constipation.
Immobility.
Impaired skin integrity.
Infection.
Interventions: Proactive measures are necessary to avert complications and ensure better health outcomes.
Nursing Considerations: Health professionals should be well-informed about these risks and pursue interventions accordingly.
