A knot under the skin is often associated with cancer. But small bumps behind the ears, neck, chest or anus can also have completely different, harmless causes. Often a cyst or a benign lipoma is the trigger. Nevertheless, changes to the tissue should always be clarified by a doctor to be able to react early in the event of an emergency. Read here which causes of lumps under the skin come into question.
Knot on the neck
Knots on the neck are usually either swollen lymph nodes or nodes in the thyroid gland. In addition, behind the nodular changes but also a cyst, an abscess or a fistula stuck. If the swelling of the lymph nodes slowly continues to increase, without the knots hurt, you should definitely consult a doctor. Such symptoms may indicate a tumor in the lymphatic system.
Swollen lymph nodes that cause pain, however, are usually caused by an infection such as a cold or tonsillitis. In order to combat the pathogens, the body's own immune system, which also includes the lymph nodes, works at full speed. Due to the increased activity, the lymph nodes can swell and hurt.
Node in the thyroid gland
Nodules on the neck do not always have to be swollen lymph nodes, but there may also be nodes in the thyroid gland. These can be very small and cause no discomfort, or be relatively large and thus easily palpable from the outside. Regardless of size, a distinction is made between cold, warm and hot knots. Cold knots barely produce hormones, while warm and hot ones are particularly active.
Warm and hot knots are usually benign, but can lead to hyperthyroidism. Even cold knots often indicate a harmless tissue change, in rare cases, but can also be behind a malignant tumor. Clarity can provide a fine needle puncture where cells are removed for closer examination.
Knot behind the ear
A knot behind the ear, similar to the neck, is often caused by a swollen lymph node. A relatively rapidly increasing, painful swelling is usually caused by an infection. Often it is a local infection that affects the ear or jaw. On the other hand, if the swelling slowly develops over a period of several weeks and the bruising is not painful, you should see a doctor to rule out a serious cause.
Knot in the chest
Similar to a lump on the neck, there is rarely a cancer behind a bump in the breast. Breast cancer is the cause in only 20 percent of the cases. Much more often, a cyst and a fibroadenoma or other harmless cause are behind the nodular tissue change,
If, after examination by the doctor, it is unclear whether it is a benign or malignant change, a histological examination is performed. Cells are removed and then examined more closely. Depending on the result, a corresponding therapy can then be initiated. Here, the possibilities range from waiting and observing to dotting (cyst) to complete removal of the knot.
Knot on the anus
Formed at the anus node, hemorrhoids or anal venous thrombosis are the most common causes. In anal venous thrombosis, blue-red nodules develop on the anus. These are caused by a blood clot that clogs a vein on the anus. Unlike hemorrhoids, which grow out of the anus, the nodes grow on the anal margin during anal venous thrombosis. The thrombosis can be very painful and make sitting unbearable. The treatment depends largely on the severity of the pain and the size of the nodules.
While anal venous thrombosis is often painful but does not bleed, hemorrhoids are the other way around: they generally cause no pain in the early stages, but may bleed. In addition, they are not covered with normal skin, but with mucous membrane. If you find yourself having hemorrhoidal anemia, you should see a doctor and talk to him about appropriate treatment.
Knot on the testicles
Behind nodes in the testicles can be various causes. Often these are relatively harmless, such as a cyst. Extended varicose veins or testicular inflammation can also cause nodular changes in the testicles. However, in some cases testicular nodules may also be a symptom of testicular cancer. Then, in contrast to an infection, the nodes often do not cause any pain. In order to recognize node-like changes as early as possible, men should feel their testicles - similar to women's breasts - regularly.
Knot under the skin
If there are knots under the skin at other parts of the body, these are often lipomas. These are benign growths of the fatty tissue. The growths themselves are harmless, but they often represent a cosmetic problem. In addition, it can cause problems when a lipoma, for example, presses on a nerve. Although lipomas are generally harmless, they should always be clarified by a doctor. Because in rare cases, behind the Knubbel also a malignant tumor - a so-called liposarcoma - stuck.
Lipomas often form in people between the ages of 40 and 60, as they produce a lot of fatty tissue during this period of their lives. They occur preferably in the neck, on the upper arms, the stomach and on the thighs. Their size can vary greatly: small lipomas have a diameter of only a few millimeters, whereas large ones can bring it to several centimeters.
In addition to a lipoma, other causes can also be behind the knots under the skin. Among others, an abscess, an inflammation of the superficial veins (thrombophlebitis), a cyst or an inflammation of the subcutaneous fatty tissue (erythema nodosum) come into question.
Nubule under the skin: what to do?
If you find a lump under your skin that persists for a long time, you should always see a doctor. Only he can tell you what's behind the nodule. But do not panic immediately: cancer is rarely the cause. Much more common are harmless structures like a benign lipoma or a cyst. Depending on the cause behind the node, various investigations can be carried out. The treatment also depends on the underlying cause.
