Cancer is a disease that occurs when abnormal cells in the body grow uncontrollably. These cells may form tumors and can spread to other parts of the body, a process called metastasis.

There are many types of cancer, including lung, breast, liver, and skin cancer. Risk factors include smoking, unhealthy diets, obesity, lack of exercise, excessive alcohol use, certain infections, and exposure to harmful chemicals or radiation.

Common warning signs may include unexplained weight loss, persistent fatigue, unusual lumps, long-lasting pain, skin changes, or a persistent cough. These symptoms do not always mean cancer, but they should be checked by a healthcare professional.

Treatment options depend on the type and stage of cancer and may include surgery, chemotherapy, radiation therapy, targeted therapy, or immunotherapy.

Although cancer cannot always be prevented, maintaining a healthy lifestyle, avoiding tobacco, exercising regularly, eating a balanced diet, and attending regular health check-ups can help reduce the risk.

Early detection and proper treatment can greatly improve the chances of successful outcomes.
