What is the difference between malignant and carcinoma

August 6, July 30, This information is not intended to replace the advice of a medical professional. You should always consult your doctor before making decisions about your health. Posted by Revere Health. Malignant Tumors Malignant tumors are cancerous. Forms of malignant cancer include: Carcinoma: begins in the skin or tissues in internal organs Sarcoma: begins in bone, fat, cartilage, muscle, blood vessels or other connective tissues in the body Leukemia: malignancy that begins in bone marrow or other blood-forming tissue, causing abnormal cells to enter the bloodstream Lymphoma and multiple myeloma: begin in cells of the immune system Central nervous system cancers: malignancies that begin in the spinal cord or brain tissues Treatments for malignant tumors includes chemotherapy , radiation therapy and immunotherapy, plus any other individual treatments your doctor may prescribe.

Then, over time, it will start to form a red lump. Lipomas are slow-growing tumors that form in fatty tissue under the skin. They can occur anywhere, but particularly the neck, shoulders, armpits, or trunk. Some have the potential, though, to become cancerous if abnormal cells continue to change and divide uncontrollably.

Colon polyps, for example, are often precancerous. Our bodies constantly produce new cells to replace old ones. Sometimes, DNA gets damaged in the process, so new cells develop abnormally.

Instead of dying off, they continue to multiply faster than the immune system can handle, forming a tumor. Cancer cells can break away from tumors and travel through the bloodstream or lymphatic system to other parts of the body. The most common cancers are carcinomas, which develop in epithelial cells.

They include the following:. Sarcomas begin in bones , soft tissues , and fibrous tissues. This can include:. Germ cell tumors begin in cells that produce eggs or sperm. They can also develop in the abdomen, chest, or brain.

Blastomas start in embryonic tissue and developing cells in the brain, eyes, or nervous stem. Children are more likely than adults to develop blastomas.

Sometimes, though, you may not know you have a tumor. It may be found during a routine screening or checkup, or during a test for some other symptom. Cancer Screening Overview. Screening Tests. Diagnosis and Staging. Questions to Ask about Your Diagnosis.

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.

Most lipomas are small, painless, rubbery, soft to the touch, and movable. 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.

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.
