What are malignant tumors?

What is an example of a malignant tumor?

Malignant Tumors: Cancerous

For example, breast cancer begins in the breast tissue and may spread to lymph nodes in the armpit if it’s not caught early enough and treated. Once breast cancer has spread to the lymph nodes, the cancer cells can travel to other areas of the body, like the liver or bones.

What are benign and malignant tumors?

Tumors can be benign (noncancerous) or malignant (cancerous). Benign tumors tend to grow slowly and do not spread. Malignant tumors can grow rapidly, invade and destroy nearby normal tissues, and spread throughout the body.

Is a malignant tumor serious?

A malignant primary tumor is more dangerous because it can grow quickly. It may grow into or spread to other parts of the brain or to the spinal cord. Malignant tumors are also sometimes called brain cancer.

Can a malignant tumor be removed?

In most cancer cases, the treatment goal is malignant tumor removal. Often two or more treatment methods are applied and selected from surgery, chemotherapy, and radiation.

What are the characteristics of malignant tumors?

A malignant neoplasm is composed of cells that look less like the normal cell of origin.

Thus, characteristics of malignant neoplasms include:

  • More rapid increase in size.
  • Less differentiation (or lack of differentiation, called anaplasia)
  • Tendency to invade surrounding tissues.
  • Ability to metastasize to distant tissues.

What health problems do malignant tumors cause?

Common symptoms include:

  • severe, persistent headaches.
  • seizures (fits)
  • persistent nausea, vomiting and drowsiness.
  • mental or behavioural changes, such as memory problems or changes in personality.
  • progressive weakness or paralysis on one side of the body, vision problems, or speech problems.

Does a malignant tumor hurt?

In its early stages, soft tissue malignant tumors rarely cause any symptoms. Because soft tissue is very elastic, the tumors can grow quite large before they are felt. The first symptom is usually a painless lump. As the tumor grows and begins to press against nearby nerves and muscles, pain or soreness can occur.

How do malignant tumors spread?

When cancer spreads, it’s called metastasis. In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body. Cancer can spread to almost anywhere in the body. But it commonly moves into your bones, liver, or lungs.
