Comprehensive Notes on Cancer: Prevention, Diagnosis, Treatment, and Survivorship
CANCER PREVENTION AND EARLY DETECTION
Limit Alcohol: Reducing alcohol intake can decrease the risk of various cancers.
Regular Physical Activity: Engaging in consistent physical activity helps maintain a healthy body weight and reduces cancer risk.
Maintain Normal Weight: Avoid obesity, as it is a significant risk factor for multiple cancer types.
Colorectal Screenings: Regular screenings help in early detection of colorectal cancer.
Regular Mammography and Pap Tests: Crucial for early detection of breast and cervical cancers, respectively.
Use Sunscreen: SPF 15 or higher recommended; avoid tanning beds to reduce skin cancer risk.
Adequate Rest: Aim for at least 8 hours of sleep per night for overall health.
Avoid Tobacco: Cigarette smoking and tobacco use are primary contributors to cancer incidence.
Balanced Diet: Emphasize vegetables, fruits, whole grains, and fiber. Limit smoked and salt-cured meats high in nitrates.
WARNING SIGNS OF CANCER
C - Change in bowel or bladder habits.
A - A sore that does not heal.
U - Unusual bleeding or discharge from any body orifice.
T - Thickening or a lump in the breast or elsewhere.
I - Indigestion or difficulty in swallowing.
O - Obvious changes in a wart or mole.
N - Nagging cough or hoarseness.
DIAGNOSIS OF CANCER
Diagnostic Plan: Involves history and physical exams, identification of risk factors, and specific diagnostic studies.
Dependence: Diagnosis depends on the suspected primary or metastatic site of cancer.
Diagnostic Studies: Used to assess disease extent, tissue of origin, and characteristics aiding treatment decisions.
Biopsy: The only definitive method for diagnosing cancer, with techniques varying by tumor location and size.
ANXIETY AND FEAR IN CANCER
Patient and Caregiver Stress: Diagnosis and treatment can induce significant anxiety.
Fear of Unknown: Uncertainty often heightens stress more than the diagnosis itself.
Active Listening: Essential in alleviating concerns; explain tests and preparations clearly.
Anxiety from Myths: Combat misconceptions like cancer being a death sentence or treatment being intolerable.
COMMUNICATION STRATEGIES
Avoid False Reassurance: Statements like "It's probably nothing" can undermine trust.
Redirecting Discussions: Avoid putting off difficult conversations; it can alienate patients.
Generalizing Experiences: Each patient’s feelings are valid and unique.
Clear Communication: Provide understandable explanations and provide written information to reinforce verbal communication.
CANCER TREATMENT
Goals
Cure: Complete removal or eradication of the cancer.
Control: Managing cancer growth and spread.
Palliation: Offering relief from symptoms without curing the disease.
Personalized Cancer Medicine
Targeted Therapy: Focuses on specific genes/proteins involved in cancer growth and survival, requiring a biopsy for identification.
SURGICAL THERAPY
Oldest Treatment: Surgical intervention is one of the earliest methods for treating cancer.
Contemporary Approach: Emphasis has shifted towards less radical surgeries.
CHEMOTHERAPY
Antineoplastic Therapy: Utilizes chemicals to systemically treat cancer.
Primary Use: Standard treatment for most solid tumors and hematologic cancers.
Dosage and Administration: Combined drugs calculated based on body surface area, utilizing various delivery methods (oral, IV, central venous access).
Preparation and Handling of Chemotherapy Agents
Occupational Hazard: Safety procedures are crucial due to potential exposure risks. Only trained personnel should handle chemotherapy.
RADIATION THERAPY
Older Nonsurgical Method: Frequently used in cancer treatments.
Delivery Methods:
External Beam Radiation: Most common; involves exposure to radiation via a machine.
Internal Radiation (Brachytherapy): Radioactive materials placed near tumors to minimize healthy tissue exposure.
NURSING MANAGEMENT IMPLICATIONS
Common Side Effects: Bone marrow suppression, fatigue, gastrointestinal problems, skin reactions, pulmonary issues, cognitive changes, and reproductive effects.
Late Effects: Patients treated with high-dose radiation or alkylating agents may face progressive, generally permanent complications, including secondary cancers.
IMMUNOTHERAPY
Mechanism: Utilizes the immune system to combat cancer, sometimes referred to as biologic therapy.
Functions: Enhances or manipulates immune responses to eliminate cancer cells.
HEMATOPOIETIC STEM CELL TRANSPLANTATION (HSCT)
Types: Includes bone marrow transplants and peripheral stem cell transplantation to allow for high doses when standard treatments fail.
Procedure: May involve multiple aspirations from the iliac crest to obtain sufficient stem cells.
COMPLICATIONS OF CANCER
Malnutrition and Infection: Constant cancer growth and side effects often lead to various health complications.
Cancer Pain Management: Assessment of pain must be taken seriously, as inadequate management can lead to worse life quality and increased caregiver burden.
CANCER SURVIVORSHIP
Increasing Numbers: Over 16.5 million cancer survivors in the U.S. Due to aging populations and advancements in treatment.
Awareness of Late Effects: Survivors should be monitored for cognitive changes, secondary cancers, and psychosocial effects.

Balanced Diet: Emphasize vegetables, fruits, whole grains, and fiber. Limit smoked and salt-cured meats high in nitrates.
Get Vaccinated: Vaccines such as those targeting HPV and Hepatitis B can lower the risk of certain cancers.
Regular Health Check-Ups: Engage in yearly health screenings to monitor any changes in health that could indicate cancer development.

Diagnostic Studies: Used to assess disease extent, tissue of origin, and characteristics aiding treatment decisions.
