Cancer is a broad term used to describe a group of diseases characterized by abnormal cell growth with the potential to invade or spread to other parts of the body. There are over 100 different types of cancer, each with its own causes, symptoms, and treatment options.

Cancer can develop in almost any organ or tissue in the body when normal cells begin to grow out of control. These abnormal cells can form a mass called a tumor. Not all tumors are cancerous; benign tumors do not spread to other parts of the body and are typically not life-threatening, while malignant tumors are cancerous and have the potential to spread (metastasize) to other areas of the body.

The exact cause of cancer is often complex and multifactorial, involving a combination of genetic, environmental, and lifestyle factors. Risk factors for cancer include tobacco use, excessive alcohol consumption, unhealthy diet, lack of physical activity, exposure to radiation or carcinogens, certain infections (such as HPV and hepatitis), and genetic predisposition.

Treatment for cancer depends on various factors, including the type and stage of cancer, as well as the patient’s overall health and preferences. Common treatment modalities include surgery, chemotherapy, radiation therapy, targeted therapy, immunotherapy, hormone therapy, and stem cell transplant. In recent years, there have been significant advancements in cancer treatment, leading to improved outcomes and survival rates for many types of cancer. Early detection through screening tests and adopting a healthy lifestyle can also play a crucial role in preventing certain cancers or detecting them at an early, more treatable stage.
