What Does A Lump Under The Armpit Mean

I Have A Lump In My Armpit. Is This Breast Cancer?

Most of the time, a lump under the armpit is an enlarged lymph node. Lymph nodes are an important part of the immune system and can swell when the body is fighting off an infection or dealing with an injury.

If the skin looks normal, but there is a bump that can be felt under the skin, the lump may be an enlarged lymph node.

It is usually advised to monitor the lump for a few days to see what happens. If the lump goes away, then the lymph node most likely became swollen in response to an infection or inflammation. Symptoms such as redness, pain, or fever accompanying the swollen lymph node can be symptoms of infection that should be checked out by a doctor.

Another common explanation for a lump under the armpit is something in the skin, such as a cyst or a blocked hair follicle.

In rare circumstances, an enlarged lymph node that has certain characteristics can be a sign of cancer.

Notice An Armpit Lump Do Not Ignore It Warns Doctor

Listen to this article

My friend recently sent in a photograph that left me worried for her! It was an unusual swelling, an armpit lump! Could it be breast cancer? That was the question she asked, pushing me to think how we humans have a tendency to think of the worst even at the slightest of health concerns. She had been ignoring a smaller version of the lump for a long time, but this sudden enlargement got her worried, naturally. Thats when we set out to find out about armpit lump causes, diagnosis and treatment.

We reached out to Dr Ch. Syama Sundari, MD,DNB Consultant Dermatologist and Cosmetologist, Aster Ramesh Hospital, Guntur, to find out more about armpit lump.

Well, a lump or swelling is a common presenting problem. sometimes a lump may also be found incidentally by the examining clinician in the course of routine examination, the expert told Health Shots.

A swelling in the underarm area or armpit feels like a discrete lump, rather than diffused swelling across the entire area.

Its possible that there are other symptoms in addition to a lump in your armpit. The medical name for armpit is axilla, so armpit lump is also called as axillary swelling, added the doctor.

Or Your Nipples Are Leaking

Is there anything more alarming than having your breasts start squirting liquid when theres no baby involved? Its normal to have some leakage during pregnancy while breastfeeding, and up to a year after weaning your baby, but if you notice any discharge any other time it needs to be evaluated by a doctor, says Dr. Patt.

Random dischargeespecially if its red or green or has an odormight mean you have a problem, including cancer of the breast or the pituitary gland, Dr. Patt explains.

/6what Does Benign Breast Lumps Mean

Benign breast lumps are non-cancerous breast lumps that cause some amount of distress.

As opposed to cancerous breast lumps, benign breast lumps can be tender and painful.

One may experience a general pain, nipple pain and/or a yellow or green discharge from the nipple.

However, some types of breast cancer can also showcase these symptoms, which is why it is best to talk to a specialist or a doctor.

Is An Armpit Lump A Symptom Of Breast Cancer

Breast Cancer Symptoms Pain In Armpit

While an armpit lump can be a symptom of breast cancer, it is relatively rare for an armpit lump to be the initial sign of breast cancer. Instead, most breast cancers appear as a mass or abnormality on the breast.

To determine whether your armpit lump is linked to breast cancer, you must consult with a healthcare provider for a physical examination.

When an armpit lump occurs, there are a few reasons that it can be a symptom of breast cancer. These factors include:

Vaccines And Armpit Lumps

Common vaccines, such as those for the flu or COVID-19, can occasionally trigger the immune system and cause the lymph nodes in your armpit to swell. This is normal and not a cause for concern. However, if the armpit lumps persist for more than a few weeks after the shot, then you should bring them to the attention of your doctor.

Other Indications That It Might Be Cancer

You know that a lump may be a sign of breast cancer. But some types, like inflammatory breast cancer, dont usually cause a lump. So, its worth knowing other signs and symptoms of breast cancer, such as:

  • swelling around your breast, armpit, or collarbone
  • dimpling of your skin, which can resemble an orange peel
  • red or discolored, dry, flaky, or thickening skin on your breast or nipple
  • unusual nipple discharge, especially blood
  • the nipple is turning inward
  • any change in size or shape of a breast

If cancer has advanced beyond your breast, symptoms may include:

  • unexplained weight loss
  • shortness of breath

Symptoms in men are very much the same. Of course, having one or more symptoms doesnt mean you have breast cancer, but the only way to know for certain is to call a doctor as quickly as possible.

Breast cancer is most common in people who:

  • with age, especially after 50
  • have a personal or family history of breast cancer
  • have their first period before 12 years old or menopause after 55 years old
  • experience physical inactivity
  • take hormonal contraceptives or hormone replacement therapy
  • consume alcohol

Its important to note that the stress of enduring racism, discrimination, and other racist systems may play a part in developing the disease beyond genetic factors.

Symptoms If Cancer Has Spread To The Bones

You may have any of these symptoms if your cancer has spread to the bones:

  • an ache or pain in the affected bone
  • breaks in the bones because they are weaker
  • breathlessness, looking pale, bruising and bleeding due to low levels of blood cells – blood cells are made in the bone marrow and can be crowded out by the cancer cells

Sometimes when bones are damaged by advanced cancer, the bones release calcium into the blood. This is called hypercalcaemia and can cause various symptoms such as:

What Does A Cancer Lump In The Armpit Feel Like


A normal lymph node should have the shape of a lima bean. It should also be somewhat firm, but still have some give to it. A cancerous lymph node will often become rock hard. It will also lose the lima bean shape and become more rounded like a marble.

If a swollen lymph node is overly firm and is not shaped like a lima bean, it could potentially be cancerous. Likewise, if the lump is obviously not in the skin, and if it persists, gets larger, and is not accompanied by signs of an infection, it may be time to seek medical attention.

Remember: It is impossible to diagnose cancer by touch so if you are concerned or notice these symptoms, you should contact your doctor. While a lump in the armpit is usually not something to worry about, and the explanation for it is usually something mild and relatively harmless, it is better to be safe and have it checked out.

What Are Lymph Nodes

You have hundreds of lymph nodes throughout your body. Your lymph nodes are part of your lymphatic system, which, in turn, is part of your immune system.

Lymph nodes are little bean-shaped structures that contain immune cells that help fight infection. Theyre connected by a system of lymph vessels that carry fluid throughout your body. As fluid passes through your lymph nodes, they filter out harmful substances.

Cancer spreads when cancer cells break away from the primary tumor. In breast cancer, these cells are most likely to reach the lymph nodes closest to the affected breast.

Usually, these lymph nodes are under the arm, but there are also clusters of lymph nodes near the collarbone and breastbone.

The ones that are closest to your breast are called sentinel lymph nodes. The nodes under your armpit are called axillary lymph nodes.

Even if cancer has reached nearby lymph nodes, it doesnt mean it has spread to other areas. But cancer that reaches the lymph system or bloodstream has a greater potential to travel to other parts of the body.

Breast cancer that has spread to lymph nodes may be treated more aggressively than if it hadnt reached these nodes.

The 5-year survival rate for breast cancer that hasnt reached nearby lymph nodes is 99 percent versus 86 percent when it has.

Types Of Lymph Node Surgery

Even if the nearby lymph nodes are not enlarged, they will still need to be checked for cancer. This can be done in two different ways.Sentinel lymph node biopsy might be needed.

Lymph node surgery is often done as part of the main surgery to remove the breast cancer, but in some cases it might be done as a separate operation.

Breast Cancer Screening At Msk

A physical exam alone cannot reliably distinguish a benign lump in the breast from a suspicious one. Thankfully, there are many options for screening:

  • A 3-D mammogram offers a detailed look at the breast in slices almost like a photo flipbook so doctors can get a very detailed picture. 3D allows us to see cancers through dense breast tissue.
  • An ultrasound uses sound waves to see lumps. It can distinguish between solid and cystic masses.
  • A contrast mammogram and an MRI both show if the lump has blood flow. Cancers typically have increased blood supply.

At MSK, we offer breast cancer screening services and programs for people at all levels of risk, with or without a history of cancer. MSKs breast cancer screening guidelines recommend that most women get a mammogram every year beginning at age 40, with annual mammography beginning earlier for women at a high risk for breast cancer.

What Is Usually The First Sign Of Breast Cancer

Painful Pea Sized Lump In Armpit

The common signs of breast cancer include:

  • A lump in the breast or in the armpits is often the first sign of breast cancer. This may be felt while in the shower. There may or may not be changes in the structure of the breast. Axillary swelling may indicate that cancer from the breast has traveled to the lymph nodes, and now there may be a lymph node invasion.

Apart from above signs below are few other sign and symptoms:

  • Changes in the nipple area, nipple retraction and inverted nipple are common warning signs of breast cancer
  • Bleeding from the nipple may be limited and difficult to see, but if an individual notices blood stains on the bra, or if the secretions are unusual, bloody or continuous, they may need urgent medical attention.
  • Change in color and/or thickening of skin on the breast that resembles an orange rind is a warning sign of breast cancer. If the breast skin changes color, typically to a pink or reddish hue that covers more than half the breast that may also be a warning sign.
  • A non-healing sore anywhere on the breast, including the nipple with or without bleeding may be a warning sign of breast cancer
  • Increased warmth in the breast with change in size and appearance of breast is a sign of breast cancer.

Breast Lump And Armpit Lump

I have 2 lumps in my breast. I got one biopsied and that was fibroadenoma. I didnt get the other one biopsied. The other one is located the the bottom part of my breast. A week ago I noticed a lump in my armpit on that same side. Its oval shaped, and it moves pretty easily, and doesnt hurt. I was freaking out. A week goes by and now I feel multiple tiny lumps under my armpit. Im terrified that these are my lymph nodes. Im not sick, I dont have an infection, so Im terrified. Everything I see online leads to breast cancer. Im only 19 years old but everything I see and hear about when it involves a breast lump and swollen lymph nodes is bad news. I havent heard any hopeful good news and I cant stop crying. I have an appointment to see my breast surgeon on Tuesday.

Just wanted to update:

This is great news, even though you don’t sound convinced. I agree with you that I would have felt happier if your consultant had found the lump, but it should have shown up on your ultrasound too.

I have had 2 bouts of breast cancer and know how lumps can disappear when you are trying to find them. Soap yourself well in your armpit and on your hand when you are in the shower, then see if you can still feel it. If you can, it might be worth seeing your GP for reassurance, as s/he will have a full report on your ultrasound from your consultant.

I’m absolutely delighted for you!Kind regards,

What Are Underarm Lumps

Underarm lumps are usually caused by swollen lymph nodes or glands that are developed under the armpits. Lymph nodes can be identified as small oval-shaped developments that form a ball-like structure.

Underarm lumps are experienced by both men and women alike, but poses more of a health risk for women in rare cases. These swollen bumps might seem scary at first, but in most cases, they are just the result of some minor issues.

To understand these lumps better and why they occur, here are some causes and symptoms that you can examine and see for yourself if your condition requires serious attention.

Will A Lump In The Armpit Go Away When Should I See A Doctor

In many cases, lumps under the armpit are caused by a swollen lymph node in other words, the bodys immune system responding to a small issue such as an infection or irritation. In many cases, a lump in the armpit will go away quickly.

However, you should get an armpit lump checked by your doctor if the lump persists for more than a week. This is especially true if the lump is accompanied by other symptoms such as:

  • persistent fever
  • unexplained weight loss

Other reasons to seek medical attention are if the lump is beneath rather than in the skin, continues to get larger, and there is no redness to indicate infection.

Symptoms If Cancer Has Spread To The Lymph Nodes

Lymph nodes are part of a system of tubes and glands in the body that filters body fluids and fights infection.

The most common symptom if cancer has spread to the lymph nodes is that they feel hard or swollen. You might have any of the following symptoms if your cancer has spread to the lymph nodes:

  • a lump or swelling under your armpit
  • swelling in your arm or hand
  • a lump or swelling in your breast bone or collar bone area

One of the first places breast cancer can spread to is the lymph nodes under the arm on the same side as the breast cancer. This is not a secondary cancer.

Outlook For Armpit Lumps

The outlook for an armpit lump depends on its cause. For example, a lump that stems from a self-limited viral infection will likely eventually go away on its own. However, a lipoma, while harmless, usually does not go away on its own. A dermatologist can help you remove it.

The outlook for an armpit lump caused by cancer depends on a variety of factors, including the stage of cancer and whether the tumors have spread to other parts of the body. For the best chance of recovery, its important you go to your doctor early on for diagnosis and treatment.

Even if you dont think the lump is harmful, its best to contact your doctor for an accurate diagnosis.
