Cancer

What is Cancer?
Cancer is not a single disease, but a broad term for over 100 different diseases. They all share one common trait: the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissue.

The Core Cause: It begins with changes (mutations) to the DNA within cells, which turn off the "stop growing" signals and allow damaged cells to multiply.

General Signs & Symptoms

Symptoms vary drastically depending on which part of the body is affected. However, some general warning signs include:

• Physical Changes: A lump or thickening under the skin.
• Unexplained Weight Loss or Gain: Significant changes without trying.
• Skin Changes: Yellowing, darkening, redness, sores that won't heal, or changes to existing moles.
• Persistent Issues: A cough, indigestion, hoarseness, or difficulty swallowing that does not go away.
• Fatigue: Extreme exhaustion that doesn't improve with rest.
• Unexplained Pain or Fevers: Persistent joint/muscle pain or frequent night sweats.

⚠️ WHEN TO SEE A DOCTOR
If you have any persistent symptoms that last longer than two weeks, make an appointment. Early detection is the most important factor in surviving cancer. Do not wait for symptoms to become unbearable.

Who is at Risk?

While anyone can develop cancer, certain factors significantly increase your risk:

• Age: Cancer can take decades to develop. The majority of people diagnosed are 65 or older.
• Lifestyle Habits: Smoking, heavy alcohol consumption, obesity, and excessive sun exposure (UV radiation).
• Genetics: A small portion of cancers (5-10%) are strictly inherited through genetic mutations (like BRCA1/BRCA2) passed down in families.
• Environment: Exposure to secondhand smoke or workplace chemicals like asbestos and benzene.
• Chronic Conditions: Conditions causing chronic inflammation, such as ulcerative colitis.

Understanding Cancer Stages

Once diagnosed, doctors determine the "Stage" of the cancer. This describes how large the tumor is and how far it has spread.

Stage	What it Means
Stage 0 (In Situ)	Abnormal cells are present but have not spread to nearby tissue. Highly curable.
Stage I, II, III	Cancer is present. The higher the number, the larger the tumor and the more it has spread into nearby tissues or lymph nodes.
Stage IV (Metastatic)	The cancer has spread (metastasized) to distant parts of the body, such as the liver, lungs, or brain.

Common Treatment Options

Treatment goals range from a complete cure to palliative care (managing symptoms). Often, a combination of therapies is used:

• Surgery: Physically removing the tumor and surrounding tissue.
• Chemotherapy: Powerful systemic drugs used to kill rapidly dividing cancer cells throughout the body.
• Radiation Therapy: High-powered energy beams (like X-rays) targeted directly at the tumor to destroy it.
• Immunotherapy (Biological Therapy): Drugs that stimulate your own immune system to recognize and attack the cancer cells.
• Targeted Therapy: Drugs that focus on the specific genetic mutations allowing the cancer cells to survive.

Lifestyle & Coping

💙 LIVING WITH CANCER
A cancer diagnosis is life-altering. Protecting your mental and physical health during treatment is vital:

• Nutrition: Treatment can alter your taste buds and appetite. Focus on nutrient-dense, easily digestible foods. Consider speaking to an oncology dietitian.
• Stay Active: Light, regular exercise (like daily walks) has been proven to reduce treatment-related fatigue and improve mental health.
• Seek Support: Do not isolate yourself. Join a local or online cancer support group. Connecting with people who truly understand the journey makes a massive difference.
