There are numerous different types of cancer. The cancer causes and symptoms can vary with the specific types of cancer. Some general cancer causes and symptoms pertain to several types of cancer.

Each specific type of cancer causes its own set of symptoms, but some cancer symptoms are similar for numerous types of cancer. Fatigue is one of the most common cancer symptoms. Cancer causes persistent fatigue that is often caused by anemia.

Another common cancer symptom is unexplained weight loss. If a person has a decreased appetite and loses ten pounds or more without dieting, the person should consult a doctor since this type of weight loss can be caused by cancer and many other diseases.

Fevers are often a signal that the immune system is strained. Cancer can cause fevers that are persistent or frequent. Not all types of cancer cause fever early in the illness, but fevers can be caused by several different types of cancer if the cancer is spreading.

Several types of cancer have pain as a symptom. Some types of cancer only cause pain when the cancer spreads and affects the nerves of the person’s body. Types of cancer often cause pain as specific part of the body such as back pain being caused by colon cancer.

Many types of cancer can cause changes in bowel habits. A cancer patient may experience diarrhea, constipation, gas, or blood in the stools. Anyone who experiences significant changes in bowel habits should consider being examined by a doctor since cancer and many other illnesses can cause these symptoms.

Different types of cancer have different causes. For example, sunburns and sun exposure increases a person’s risk of skin cancer, but it does not increase the risk of other types of cancer like lung cancer or pancreatic cancer.

A genetic predisposition to a type of cancer is a common cause of many types of cancer. If a person has a family history for a particular type of cancer, they are at increased risk of developing cancer.

There are also other contributing factors to cancer. A sedentary lifestyle and poor diet can make someone prone to cancer especially if they have a family history of the cancer and have been exposed to carcinogens that caused the cancer.
