Adenomas — found on the surface of the GI tract. People can carry a benign tumor for their entire life without needing treatment. Sometimes these tumors will need to be removed as they could cause residual damage to the body and possibly become cancerous. Malignant tumors are very likely to invade other organs. The term for that process is metastasize. These tumors will grow faster than a benign tumor and are more likely to destroy the organs.
Malignant cells have a unique ability. They can actually make enzymes that will dissolve tissue in the body. Since there are no good tumors, if a tumor is found by your doctor, you will need to have a pathology examination. Case Files Collection. Clinical Sports Medicine Collection. Davis AT Collection.

Learn more about fibroadenomas of the breast here. Fibroids , or fibromas, are benign tumors that can grow on the fibrous or connective tissue of any organ.
Some fibromas can cause symptoms and may need surgery. In rare cases, fibroids can change and become fibrosarcomas. These are cancerous. Learn more about dermatofibromas. They are often present at birth and disappear during childhood. Hemangiomas do not usually need treatment, but laser surgery and other options are available if they do not go away.

They often appear on the back, shoulders, arms, buttocks, and the tops of the legs. Types of lipoma include fibrolipomas, which contain fat cells and fibrous connective tissue, and angiolipomas, which appear under the skin. Find out more about angiolipomas here. Sometimes, actinic keratosis will transform into squamous cell carcinoma , so doctors usually recommend treating it.
In cervical dysplasia, a change occurs in the cells that line the cervix. A doctor may find these cells during a Pap smear. Cervical dysplasia often stems from the human papillomavirus HPV , an infection that is common in young people. The cells are not cancerous, but they may become malignant 10—30 years later, resulting in cervical cancer. A surgeon may remove the cells using freezing techniques or by taking a cone of tissue from the cervix.
These growths occur in the bronchi, the tubes that carry air into the lungs. The lining of the bronchi contains glandular cells. In some people, including smokers, these can change and become squamous cells, or cancer.
They should also monitor the patches for changes and quit smoking or chewing tobacco, if relevant. If a doctor believes that the patches could become cancerous, they may use a laser or surgical scalpel to remove them.
Malignant tumors are cancerous. They develop when cells grow uncontrollably. If the cells continue to grow and spread, the disease can become life threatening. Malignant tumors can grow quickly and spread to other parts of the body in a process called metastasis. The cancer cells that move to other parts of the body are the same as the original ones, but they have the ability to invade other organs.
If lung cancer spreads to the liver, for example, the cancer cells in the liver are still lung cancer cells.
