Tumors and other growths


Tumor means lump. Tumors can sometimes be caused by cancer, but most tumors are not cancerous. There are also many other types of growths that can be obtained on the body and in the body. Most people can have and still feel good.

You can read more about cancer in the text What is cancer? This text provides examples of tumors and other growths that are mostly benign, also called benignly.

A benign tumor or outgrowth grows in one place without spreading. It may still need to be removed, for example, if it becomes large or infected.

What is a tumor?

A tumor means that cells somewhere in the body or on the body have begun to multiply. 

Benign tumors

Most tumors are benign. Benign tumors are easy to remove if needed. Some benign tumors can become cancerous tumors, such as polyps in the gut.

Cancer Tumors

A cancer tumor is also called a malignant tumor. It can grow into other organs and body tissues and usually also spread in the body through the lymph fluid and blood.

Examples of tumors and growths

Here you can read about examples of benign tumors and tubers or growths that can be a blister or a swelling after an injury. 

Adenoma – glandular tumor

An adenoma is the same as a glandular tumor. It is a benign tumor in a gland. Glands are organs that make different kinds of secretions. For example, secretions are saliva, sweat, hormones or substances that break down food in the stomach and intestines. Some adenomas can secrete large amounts of hormones or be precursors to cancer. In that case, they are removed.


A cyst is a fluid-filled bladder. Cysts can be of different sizes. They can sit in different places in the body, for example in the ovaries, in the breasts or in the liver. Cysts are usually removed if they touch organs or other parts of the body.

Fibroadenoma – connective tissue nodule

Fibroadenoma is a benign lump in the connective tissue of the breast. Fibroadenoma is due to the fact that some of the breast can grow faster than the surrounding tissue. You may be operated on if the fibroadenoma is large or in pain.


A fibroma is a benign connective tissue tumor that can be formed anywhere on the body. It may look like a lump or elevation or as a protruding birthmark fixed with the same color as the other skin. Fibroma rarely needs to be treated.


A  birthmark  is a benign tumor that can be formed anywhere on the body. It can also be called liver spots. Almost all birthmarks are harmless, but sometimes a birthmark can develop into malignant melanoma. Therefore, it is important that you pay attention to whether you have birthmarks that are changing. Then you need to be examined.

Birthmarks are an example of pigmented skin changes. Pigmented means that the skin change has a darker color than the other skin. There are many other pigmented skin changes that are benign and that are more common the older you get. You can read more about benign skin changes here.


The ganglion is also called the late knot. It is a rise caused by fluid formed at a joint, such as the wrist. Gangler’s usually disappearing without treatment within a few weeks.

Benign prostate enlargement means that the prostate has grown in size. It is common when you get older. Sometimes you may have problems that need to be treated. Benign prostate enlargement has nothing to do with prostate cancer, although the symptoms can sometimes be the same. 


A hemangioma is a benign tumor of blood vessels that can occur inside the body or on the skin. An example of hemangioma is a so-called strawberry brand. Strawberries are most common in children up to one year. Most hemangiomas cause no problems and disappear without treatment.

Corn and hardiness

Hardening can be formed if you use shoes that are too tight or that press against the foot in some other way. Then the skin becomes hard and thick. An ear of corn can be formed if the hardening is loaded or worn for a long time. Hardens and corns can hurt. Most often you can treat yourself.


A  lipoma is a fat tuber that you can get in the skin anywhere on the body. Lumps do not need to be treated.

A polyp may be a benign tumor or a swelling due to inflammation. A polyp grows out of the skin or a mucous membrane and looks like a bud or a stalk. You can get polyps, for example, in the nose, on the vocal cords, in the bladder, in the stomach or in the intestine. For safety reasons, polyps in the intestine, for example, are usually operated on because they can sometimes develop into cancer.

Thyroid cyst – posterior

A sebaceous glandular cyst can also be called atheroma. It is a benign cyst that contains sebum. It occurs when the opening from a sebaceous gland into the skin has become clogged. A sebaceous gland cyst can be formed anywhere on the body. They are most common where hair grows, especially in the scalp. A sebaceous cyst can be removed if it causes discomfort.
