Cancer can be caused by genetic mutations, tobacco use, unhealthy diet, radiation, infections, environmental exposures, and inherited genetic factors.

Some common cancers include breast cancer, lung cancer, prostate cancer, colorectal cancer, and skin cancer.

Common warning signs include unexplained weight loss, persistent fatigue, unusual lumps, prolonged cough, abnormal bleeding, and changes in skin or moles.

Some cancers run in families due to inherited gene mutations, but most cancers occur due to lifestyle and environmental factors.

While not all cancers are preventable, healthy lifestyle choices such as avoiding tobacco, maintaining a healthy weight, exercising, and regular screenings can reduce risk.

Cancer screening tests detect cancer before symptoms appear. Examples include mammograms, Pap tests, colonoscopy, and PSA tests.

A biopsy is a medical test in which a small sample of tissue is removed and examined under a microscope to check for cancer cells.

Cancer staging describes how much cancer is in the body and whether it has spread.

Common treatments include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapy.

Chemotherapy uses drugs to kill or stop the growth of cancer cells.

Radiation therapy uses high-energy rays to destroy cancer cells and shrink tumors.

Immunotherapy helps the body’s immune system recognize and fight cancer cells.

Targeted therapy uses drugs that specifically attack cancer cells without harming many normal cells.

Yes. This process is called metastasis, where cancer cells travel through blood or lymphatic systems to other organs.

No. Cancer cannot spread from one person to another through contact.

Yes. Smoking, alcohol consumption, diet, physical inactivity, and obesity significantly affect cancer risk.

Yes. Smoking is the leading cause of lung cancer and increases the risk of many other cancers.

A balanced diet rich in fruits, vegetables, and whole grains may help reduce cancer risk.

A tumor is an abnormal mass of tissue. Tumors can be benign (non-cancerous) or malignant (cancerous).

Benign tumors do not spread, while malignant tumors invade nearby tissues and may spread to other organs.

Doctors use tests such as imaging scans, blood tests, biopsies, and physical examinations to diagnose cancer.

Risk factors include age, genetics, smoking, radiation exposure, infections, and environmental toxins.

Many cancers can be cured if detected early and treated effectively.

Remission means that cancer signs and symptoms have reduced or disappeared after treatment.

Side effects may include fatigue, nausea, hair loss, pain, weakened immunity, and appetite changes.

Patients can manage side effects with medications, proper nutrition, rest, and guidance from healthcare professionals.

Palliative care focuses on improving quality of life by managing pain and symptoms during serious illness.

Yes. Some cancers may return after treatment, which is why follow-up care is important.

Follow-up visits help doctors monitor recovery, detect recurrence early, and manage long-term side effects.
