Cancer is a broad term that describes a group of diseases characterized by the uncontrolled growth of abnormal cells. It can affect any part of the body, but it most commonly affects the lungs, breast, prostate, skin, gastrointestinal tract, and lymphatic system. Depending on where in the body it occurs, cancer can cause symptoms such as pain, fatigue, weight loss, fever, and difficulty breathing. The type of treatment will depend on the specific location and stage of the cancer. In some cases, surgery may be recommended, while others may require chemotherapy or radiation therapy. Ultimately, the goal of treatment is to remove all traces of cancerous cells from the body.
