The difference between a mass and a tumor

There is a big difference between a lump and a tumor. A lump is not necessarily a tumor or cancer. Some may just be mild nodules and lumps. The lump can be recovered with medication and anti-inflammatory measures, but the recovery of tumors and cancer may not be as simple as taking medication alone. It may also require a combination of other methods.

A lump, a mass, or a mass is not necessarily a tumor or cancer, but cancer is often preceded by a lump, a mass, or a mass. Various types of small nodules or lumps can often be felt on the superficial skin of the human body.

If the diameter of a lump is less than 1 cm, it is generally difficult to accurately judge by just touching it with your hand . If the diameter is greater than 1 cm, you should pay attention. If the lump does not change significantly in shape and size for a long time, it is generally benign. If the lump grows rapidly in the near future, the possibility of malignancy should be ruled out.

Benign masses generally have regular shapes and smooth surfaces. Malignant masses may appear cauliflower-like, crater-like ulcers, uneven nodules, etc. Benign masses are generally soft, such as lipomas.

Malignant masses are generally hard. The hardness of lymphoma is generally intermediate and tough. The boundaries of a benign mass are clear and distinct from the surrounding tissues. Malignant tumors are generally prone to locally invade adjacent tissues or organs, and have unclear boundaries with the tissues next to them. Benign masses can generally be moved by pushing, while malignant masses are tightly attached to the bottom and surrounding areas and are in a fixed position, making them difficult to move.

Polyps refer to growths that grow on the surface of human tissue. Modern medicine usually refers to the growths that grow on the surface of human mucosa as polyps, including hyperplastic, inflammatory, hamartomas, adenomas and other tumors. Polyps are a type of benign tumor, but some of them have a tendency to become malignant. Cysts that grow under the skin, lipomas in adipose tissue, myomas in muscles, etc. can also cause bulges on the body surface, but they are not classified as polyps. In medicine, it is usually named according to the location where it appears. For example, those that grow on the vocal cords are called "vocal cord polyps", those that appear on the stomach wall are called "gastric polyps", those in the intestinal cavity are called "intestinal polyps", and so on.
