Armpit lumps (big or small) are very common and are normally brought on by a swollen lymph node or gland under the armpit. However, there are lots of other causes for armpit lumps, a few of which may need treatment.
Other names of the condition are: Lump in the armpit; Localized lymphadenopathy – armpit; Axillary lymphadenopathy; Axillary lymph enlargement; Lymph nodes enlargement – axillary; Axillary abscess.
An armpit lump may refer to the enhancement of at least one of the lymph nodes under your arm. Lymph nodes are small, oval-shaped structures that lie throughout the body’s lymphatic system. They play an essential role in your body’s body immune system.
An armpit lump may feel little. In other cases, it may be very obvious. Armpit lumps may be triggered by cysts, infection, or irritation due to shaving or antiperspirant usage. However, these lumps might also suggest a serious underlying health condition.
Look for medical attention if you have an armpit lump that slowly ends up being enlarged, is or isn’t painful, or doesn’t disappear.
Causes of Armpit Lumps
The majority of lumps are safe and are typically the outcome of unusual tissue growth. However, armpit lumps can be related to a more serious underlying health problem. You need to have your doctor examine any uncommon lumps you have.
The most common causes of armpit lumps are:
- bacterial or viral infections
- lipomas (typically harmless, benign fat tissue growths).
- a fibroadenoma (noncancerous fibrous tissue growth).
- hidradenitis suppurativa.
- allergies.
- adverse reactions to vaccinations.
- fungal infections.
- breast cancer.
- lymphoma (cancer of the lymphatic system).
- leukemia (cancer of the blood cells).
- systemic lupus erythematosus (an autoimmune disease that targets your joints and organs).
The armpit is a good place for a swollen lymph node, and they generally swell up in action to an infection. Sometimes when this takes place, the node injures, but often it doesn’t. In some cases you’re aware of the infection, however often you’re not. Once the infection is over, the lymph node can take 3 weeks or more to shrink back to normal, but often a node will stay harmlessly swollen and never ever go back to normal.
Causes of Armpit Lumps in Details
Most of the factors for a lump in the armpit are pretty harmless. Here are the main reasons for the appearance of bumps in the armpit in men and women (although women have this problem more often, as we will discuss below):
It’s a cyst
If you frequently shave your underarms, the inflammation to this tender skin and hair follicles can result in a cyst or abscess. If you have a cyst, the lump in your armpit may be painful. If that’s the case, see your doc who can recommend a number of treatments, including injections to reduce swelling, drainage, or perhaps surgical cyst removal.

It’s a lipoma
First, keep in mind that a lipoma– a benign fatty growth — is not lymphoma, a type of cancer. (That ought to relieve your worries.) To know if it’s a lipoma that you have, give it a touch. It’s like a “rubbery bulge that feels like it can move.” Lipomas are slow-growing and affect 1 in 1,000 people, especially those in middle-age. A lipoma might not need to be dealt with at all unless the lump in your armpit genuinely troubles you, in which case, your doctor can eliminate it.
It’s an infection
You’ve got lymph nodes throughout your body, and these convenient body immune system guards can filter out viruses and bacteria. When you’re encumbered a disease, they can swell– and there occur to be lymph nodes in your armpits. You might discover that the lump in your armpit is tender and the size of a pea or bean. However, the underlying cause can be any variety of problems, from an ordinary cold to more severe problems, like HIV, mono, lupus, or rheumatoid arthritis.
It’s an inflamed sweat gland
Everybody understands about sweaty pits. When sweat-producing glands or hair follicles get blocked, bacteria can sweep in and produce a cyst that later on bursts, contaminating even more hair follicles. If the cycle repeats, it can turn into a chronic skin problem called hidradenitis– this hits up to three percent of people in the United States. This network of cysts may be itchy, painful, and even affect your lifestyle. Although there’s no cure for hidradenitis, your medical professional can prescribe medication or other therapies like laser hair removal to improve your convenience.
It’s a breast infection
If you’re currently breastfeeding, you’ve no doubt heard the horror stories about mastitis, an inflammation of breast tissue. You might feel swelling, pain, and lumps in your breast, but the infection can also enlarge the lymph nodes in your armpit, notes the U.S. National Library of Medicine. Women typically feel as if they have the influenza.
Keep in mind: if you are not breastfeeding but think you have this type of infection, see your physician. She will want to eliminate other, serious causes, consisting of breast cancer.
It’s cat scratch disease
Strangely, feline scratch fever is a real thing. This funny-sounding condition is among the possible culprits behind an armpit lump. About half of cats carry a germs called Bartonella henselae, which they can spread via a scratch. As soon as the bacteria enters your skin, you can develop an infection that triggers the lymph nodes in your underarm to swell. The treatment? Wait it out, or if it persists, antibiotics.
Armpit Lumps in Women
Armpit lumps can happen in men and women of any ages. Nevertheless, a lump under the arm might suggest breast cancer. Women ought to perform monthly breast self-exams and report any breast lumps to a physician immediately.
Keep in mind that breasts go through hormonal changes during the menstrual cycle and might tend to feel more tender or lumpy during this time. This is considered to be totally normal. For the most accurate outcomes, perform breast self-exams about one to three days after your period ends.
Another prospective cause of armpit lumps in women, which tend to likewise take place near the breast and groin areas, is hidradenitis suppurativa. This chronic condition includes blocking and inflammation near apocrine glands of hair roots in the skin, commonly triggering painful boil-like lumps that fill with pus, leak, and potentially even become infected.
Threats for having this condition consist of tobacco cigarette smoking, family history, and obesity. Although the precise cause is not known, it is believed that perhaps hormone changes of puberty and/or the immune system reacting too highly to the hair roots becoming clogged up and irritated. Men can likewise have hidradenitis suppurativa, however it is a lot more common in women.
What Does a Large Lump in Armpit Mean? Is It Dangerous?
Lumps that change in size gradually or that do not go away might be symptoms of more major conditions such as:
- breast cancer
- lymphoma
- leukemia
Any new or recently found lump on the body could cause concern. Nevertheless, not all lumps are harmful or even painful. The severity of a lump can be best determined through medical exam and in some cases additional testing.
Indication that may show a more severe armpit lump consist of:
- progressive enlargement

If an individual experiences or notices any of these symptoms, or has any doubts about the lump, they ought to see their medical professional as quickly as possible who can dismiss more severe causes. Obviously, any uncommon lumps must be carefully examined.
