<human>: I want to know what are the different types of cancer.
<bot>: There are many different types of cancer, each with its own characteristics and treatment options. Some common cancers include breast cancer, prostate cancer, lung cancer, colon cancer, skin cancer, lymphoma, leukemia, and bladder cancer. Each type of cancer is caused by a mutation in a particular gene or group of genes that causes cells to grow out of control. The type and severity of symptoms can vary depending on the type of cancer, but some common signs and symptoms may include changes in appetite, weight loss, fatigue, pain, and difficulty sleeping. Treatment for cancer depends on the type and stage of the disease, as well as the patient's health and preferences.
