Question

What is neoplasm?

Answer 1

Neoplasm is nothing but the abnormal and excessive growth of the neoplasia of the tissue, the growth of this neoplasia is uncoordinated and is different from that of surrounding cells, and this abnormality persists, even after removal of the trigger, and this abnormal growth form a tissue called a tumor.

Complete answer:
Neoplasia is mainly of four types.
- Before the tissue reaches the stage of neoplasia, they first form the other types of conditions of the cells called metaplasia or dysplasia.
- Neoplasm is mainly because of the accumulation of genetic and epigenetic factors in the cells, that cause the cells to divide abnormally, and any mutations during cell divisions cause the tumors, but the neoplasms do not form the tumors.
- Neoplasms are of mainly 3 types, they are Benign, potentially malignant, and malignant.
- Benign neoplasm is mainly circumscribed and localized, and they do not transform into cancer.
- Potentially malignant: This includes the carcinoma in situ, they do not invade or destroy the tissues, but in the future, they transform into cancers.
- Malignant neoplasm is nothing but cancers, they invade and destroys the tissue and they are metastatic, if they can be untreated or if they are not responded to the treatment, they are proven fatal, and there are secondary neoplasms which are produce by the primary cancerous cells or by any other irrelevant cells, which are also treated only by radiotherapy and chemotherapy.
- DNA damage is considered as the primary responsibility of the Malignant neoplasms.

Note: There is a difference between the tumor and the neoplasms, where the tumor is a non specific tissue, and that is a general term used for the mass of tissue, and mean that they are harmless, and the neoplasm is of different types, they can be benign or malignant growth.
