The skin under your arms is more sensitive than other parts of your body. This is because the skin is thinner and more easily irritated. Irritation, infection, dermatitis, and other skin problems can cause the skin under your arms to feel itchy and uncomfortable. In some cases, this itching can also be a sign of cancer.
Everyone feels itchy in the armpit area from time to time. This area of skin is very susceptible to irritation not only because it is thin but also because sweat accumulates easily, according to the health website Healthline (USA).
People should shower after exercising to avoid sweat irritating the skin under the arms.
Signs of some cancers
Persistent armpit itching that doesn't go away is sometimes a sign of certain cancers, such as inflammatory breast cancer or lymphoma, a type of blood cancer.
Lymphoma is a type of blood cancer that causes an overgrowth of white blood cells. One of the common symptoms of the disease is swollen lymph nodes in the armpits, neck, and groin. These areas may also be itchy. In some cases, the itching can be all over the body.
In addition to swollen lymph nodes and itching, other symptoms of the disease include fever, chills, night sweats, unexplained weight loss, fatigue, and lack of energy.
Experts say there are about 70 types of lymphoma, mainly divided into two groups: Hodgkin lymphoma and non-Hodgkin lymphoma. Research shows that among patients with lymphoma, more than 30% are Hodgkin lymphoma and 15% are non-Hodgkin lymphoma.
Inflammatory breast cancer, on the other hand, is a rare type of cancer that can cause armpit itching. Many cases of inflammatory breast cancer are initially diagnosed as an infection, and then breast cancer is discovered later. The cause is swelling, redness, pain, and itching of the breast.
Itching under the armpit is completely normal. However, if the itching is persistent, you have tried everything but it still does not go away, and it is accompanied by symptoms of early stage cancer such as fatigue, unexplained weight loss, and the appearance of unusual lumps, you should see a doctor soon for a check-up.
Itchy armpits are also caused by bacteria and fungi.
In most cases, armpit itching is caused by bacteria and fungi. To prevent these microorganisms from growing, people should keep their underarms cool and dry, shower immediately after exercise, and dry their armpits thoroughly. Clothing materials should be breathable and absorbent, such as cotton. Wearing tank tops or loose-fitting T-shirts can help reduce sweating, thereby keeping the skin under the arms dry, according to Healthline.
