What is Cancer?

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. If not treated, these cells can invade surrounding tissues and spread to other parts of the body through the blood and lymphatic systems. It can affect nearly any organ or tissue in the body, leading to a variety of health complications.

Classify Cancer

Illness: Cancer is classified as a chronic illness that arises when genetic changes disrupt normal cell growth and division. These abnormalities result in tumors (solid masses) or blood-based malignancies like leukemia.

Cancer Statistics

Cancer is one of the leading causes of death globally, responsible for approximately 10 million deaths in 2020. An estimated 19.3 million new cases are diagnosed annually worldwide. In the U.S., 1 in 3 people will develop cancer in their lifetime, with lung, breast, and prostate cancers being the most common.

Types of Cancer

1. Carcinoma: Cancer that begins in the skin or tissues lining internal organs (e.g., breast, lung).
2. Sarcoma: Cancer of the connective tissues like bone, muscle, or fat.
3. Leukemia: Cancer of the blood-forming tissues, including the bone marrow.
4. Lymphoma: Cancer of the lymphatic system.
5. Melanoma: Cancer of the pigment-producing cells in the skin.
6. Brain and Spinal Cord Tumors: Includes gliomas and meningiomas.

Health Signs and Symptoms

Early Signs:

• Persistent fatigue.
• Unexplained weight loss or gain.

Common Symptoms:

• Lumps or swelling.
• Persistent cough or trouble breathing.
• Changes in bowel or bladder habits.
• Unexplained bleeding or bruising.
• Persistent pain.
• Skin changes, such as unusual moles.

Anatomy and Physiology

Cancer can affect nearly all body systems, but common areas include:

• Skin: Melanomas and carcinomas.
• Organs: Lungs, liver, kidneys, and pancreas.
• Blood and Bone Marrow: Leukemia, lymphoma.
• Reproductive Organs: Prostate, breast, and ovarian cancers.
• Digestive System: Stomach, colon, and rectal cancers.

Causes

Brief Description: Cancer results from mutations in genes that control cell growth and repair. These mutations can be inherited or acquired due to lifestyle, environmental factors, or infections.

Common Causes:

1. Genetic Mutations: Inherited or spontaneous.
2. Lifestyle Factors: Smoking, alcohol use, poor diet.
3. Environmental Exposures: Radiation, chemicals, and carcinogens.
4. Infections: HPV, hepatitis B and C.
5. Chronic Inflammation: Long-term inflammation can lead to abnormal cell growth.

Cancer Stages

1. Stage 0: Abnormal cells remain in their original location (in situ).
2. Stage I: Localized cancer, confined to the primary site.
3. Stage II: Larger tumor, may involve nearby lymph nodes.
4. Stage III: Advanced cancer with regional spread.
5. Stage IV: Cancer has metastasized to distant organs.

Prevention

• Avoid smoking and limit alcohol consumption.
• Maintain a healthy diet rich in fruits, vegetables, and whole grains.
• Engage in regular physical activity.
• Protect skin from UV radiation by wearing sunscreen.
• Get vaccinated against cancer-causing infections (e.g., HPV, Hepatitis B).
• Attend regular screenings for early detection.

Cancer Diagnosis

Diagnosis typically involves a combination of imaging tests, biopsies, and blood tests. Early detection through routine screenings can significantly improve outcomes.

Tests & Examinations

• Imaging: X-rays, CT scans, MRI, and PET scans.
• Biopsy: Tissue sample analysis to confirm malignancy.
• Blood Tests: Check for tumor markers like PSA or CA-125.
• Endoscopy: Visualize internal organs like the colon or stomach.

Health Professionals

1. Oncologists: Specialists in cancer diagnosis and treatment.
2. Surgeons: Remove tumors or affected tissues.
3. Radiologists: Experts in imaging and radiation therapy.
4. Hematologists: Focus on blood-related cancers.
5. Palliative Care Specialists: Manage symptoms and improve quality of life.
6. Dietitians: Help with nutritional support during treatment.

Reasons to See a Professional

• Persistent or unexplained symptoms.
• Family history of cancer.
• Abnormal screening test results.
• Concerns about genetic risk factors.

Process to Find the Right Professional

• Request referrals from primary care physicians.
• Search for board-certified oncologists.
• Research hospital or cancer center affiliations.
• Read reviews and testimonials from other patients.

Visit Preparation

• Record symptoms, their duration, and any changes.
• List all medications, supplements, and family history.
• Bring copies of any previous test results or imaging.
