which are different type of tumors
Answers
There are two general types of tumors:
benign (non-cancerous) tumors and malignant (cancerous) tumors.
A benign tumor is composed of cells that will not invade other unrelated tissues or organs of the body, although it may continue to grow in size abnormally.

Outlook
A tumor is a mass or lump of tissue that may resemble swelling. Not all tumors are cancerous, but it is a good idea to see a doctor if one appears.
The National Cancer Institute define a tumor as “an abnormal mass of tissue that results when cells divide more than they should or do not die when they should.”
In a healthy body, cells grow, divide, and replace each other in the body. As new cells form, the old ones die. When a person has cancer, new cells form when the body does not need them. If there are too many new cells, a group of cells, or tumor, can develop.
Although some tumors are benign and consist of noncancerous cells, others are malignant. Malignant tumors are cancerous, and the cells can spread to other parts of the body.
What is a tumor?
A tumor develops when cells reproduce too quickly.
Tumors can vary in size from a tiny nodule to a large mass, depending on the type, and they can appear almost anywhere on the body.
Types
Fibroids are a type of benign tumor.

There are three main types of tumor:
Benign: These are not cancerous. They either cannot spread or grow, or they do so very slowly. If a doctor removes them, they do not generally return.
Premalignant: In these tumors, the cells are not yet cancerous, but they have the potential to become malignant.
Malignant: Malignant tumors are cancerous. The cells can grow and spread to other parts of the body.
It is not always clear how a tumor will act in the future. Some benign tumors can become premalignant and then malignant. For this reason, it is best to monitor any growth.
