Lump: Causes, Symptoms, Types & Tests

A lump is a bump, growth, or swelling that occurs in or under the skin or in other parts of the body and is unusual. There are numerous causes of lumps, and some lumps have no significance, while others may require medical attention. This diagnostic service is helpful in healthcare professionals' research of different health issues at MolecularDiagnostics and Therapy. By knowing the causes of lumps, the symptoms of lumps, what types of lumps exist, and what tests are performed for a lump, people can have a better idea of when it might be time for a medical consultation. Small lumps are not necessarily a serious problem. But when a new lump that doesn't go away is painful, grows quickly, or is unusual, it should be checked by a trained health care provider.

What Is a Lump?

Lump – an area of swelling or tissue that has a sensation different from that of the surrounding area. It can be soft, firm, smooth, irregular, and/or painful. There are ways to notice some lumps; others will only be noticed on touch. Lumps may develop in the neck, underarms, and in the breasts, abdomen, back, groin, and limbs. These attributes can be helpful when the doctor is conducting physical exams.

Common Lump Causes

There are a number of possible causes for lumps, and the cause may depend on the size and nature of the lump. An enlarged lymph node is a common cause. Infection or inflammation can cause lymph nodes to swell. Another common cause is cysts. A cyst is an enclosed bag that contains either a liquid or other material. Cysts may form in various tissues and sometimes may become inflamed or infected. 

A lipoma is a smooth fatty lump that forms below the skin. Growth tends to be slow and is almost always benign. Other injuries may cause swelling or a lump at the injury site. An area of firmness may occur after an injury, due to inflammation or scar tissue. Hernias, tumours, and inflammatory conditions are other possible causes. Many similar-appearing lumps are caused by many different conditions, so it might be necessary to seek professional help to find out what is causing the lump.

Common Lump Symptoms

The lump symptoms will differ depending on the cause of the lump. Other lumps are painless and can be found by accident. Others may result in tenderness, discomfort, redness, warmth, or swelling. Swollen areas from infections can sometimes be accompanied by a fever or other symptoms of infection. Some changes over time are also important. If a lump persists or grows, or pain occurs, or if the lump changes in appearance or doesn't go away, you should talk to a healthcare provider. If present in conjunction with other persistent or otherwise unexplained symptoms, the latter should also be noted in the medical consultation.

Types of Lumps

There are several types of lumps, depending on their underlying cause. Cysts are closed sacs filled with or lacking fluid or other contents and can grow anywhere in the body. Typically, lipomas develop as slow-growing, soft masses from fat under the skin. Enlarged lymph nodes can form as a result of an infection or inflammation response of the immune system. Pus can sometimes accumulate in infected areas and lead to the formation of an abscess, which can cause pain, swelling, redness, and warmth. 

Hernias are the occurrence of tissue protrusion through a weak portion of the surrounding tissue and/or weakened portions of surrounding muscle and can be visibly seen as a bulge. Some can be a harmless lump; others may need further investigation. So, if necessary, the medical assessment of the specific type of lump should be conducted through appropriate examination.

When Should a Lump Be Evaluated?

While many lumps are harmless, some are not and require some type of medical intervention. If the lump has appeared recently, has increased in size, is particularly firm, does not move, hurts, or there are other symptoms, seek help from a healthcare professional. The type of evaluation can be determined by the location and physical characteristics of the lump. Observation, laboratory tests, imaging, or other diagnostic tests may be recommended, depending on the situation.

Tests for Lump

The tests that may be required for a lump are determined by what is suspected, the site, size, and nature of the lump. The first step is often a physical examination. The size, shape, texture, mobility, tenderness, and adjacent tissue may be evaluated by a healthcare worker. An ultrasound will be performed to see if a lump seems fluid-filled or solid. Additional imaging tests might also be desired depending on the setting and clinical results. In some cases, blood tests can help detect signs of infection, inflammation, or other factors relevant to the lump. Biopsies might be suggested in some cases. 

A biopsy is a process of taking a small piece of tissue or cells for analysis. This can help give more information regarding the type of lump. In addition, specialised molecular diagnostic methods can be used in individual cases where there is a need for a particular disease or abnormality to be investigated. Not all lumps need the same testing, so be sure to follow your doctor's recommendation.

Why Proper Diagnosis Is Important

It can be difficult to determine the cause of a lump based on its appearance and feel alone. Signs can be identical with different conditions, and therefore a professional evaluation is important when a lump remains, or if any changes are observed that are concerning. Additional information from appropriate diagnostic testing can assist the health care provider in determining whether additional diagnostics or management may be warranted.

Conclusion

Other causes of a lump include cysts, swollen lymph nodes, lipomas, infections, injuries, hernias, or various other conditions. Knowing the reasons why lumps form, symptoms of lumps, the different types of lumps, and testing for lumps can help individuals determine whether they should seek professional medical attention for their lumps. It's best to avoid self-diagnosing a new, persistent, growing, painful, or unusual lump, although such symptoms might initially be ignored.
