What Does a Cancer Lump Feel Like in the Armpit? Symptoms, Causes, and Diagnosis

Have you ever felt a lump in your armpit and wondered what it could be? While armpit lumps are not uncommon, it’s important to know when to take them seriously. One of the potential causes of these lumps is cancer – and it’s vital to know what to look out for.

So, what does a cancer lump feel like in the armpit? Firstly, it’s important to note that not all armpit lumps are cancerous. However, cancerous lumps tend to feel harder and more fixed than non-cancerous lumps. They may also be irregularly shaped and not tender to the touch.

If you do come across a lump that fits this description, it’s important to seek medical attention as soon as possible. While it’s understandable to feel worried, remember that catching cancer early on greatly increases one’s chances of successful treatment. So, make sure to keep an eye out for any unusual lumps in your armpit and don’t hesitate to visit your doctor if you have any concerns.

Signs and Symptoms of Breast Cancer

Knowing the signs and symptoms of breast cancer is crucial in detecting it early on and seeking treatment promptly. One common symptom is the presence of a lump in the breast or armpit that feels different from the surrounding tissue.

A cancer lump in the armpit, known as axillary lymph nodes, may feel like a small, hard, and non-mobile pea-shaped mass. This lump may or may not be painful to the touch and can be accompanied by swelling or tenderness in the same area.

  • Breast cancer may cause nipple changes, including inversion, discharge, or redness and scaling.
  • Changes in breast size, shape, or texture may also signal the presence of cancer.
  • Skin changes, such as dimpling or puckering, may occur on the breast’s surface.

If you notice any of these symptoms, it is advisable to visit a doctor for further evaluation. Early detection often leads to more successful treatment and increases the likelihood of cure.

Additionally, it is essential to be aware of risk factors that may increase your chances of developing breast cancer. These include hormonal imbalances, age, genetics, and lifestyle factors such as alcohol and tobacco use.

Hormonal imbalances
Alcohol and tobacco use

Even if you do not experience any symptoms or have any risk factors, it is still recommended to undergo regular check-ups and screening tests, such as mammograms, to detect any abnormalities early on. It is vital to take care of your breast health to prevent any potential complications and ensure overall well-being.

Different Types of Breast Cancer

There are several types of breast cancer, each with unique characteristics and treatment approaches. It is important to understand the different types so that one can make informed decisions about their treatment options.

  • Ductal carcinoma in situ (DCIS): This is the earliest stage of breast cancer, where cancer cells are confined to the milk ducts in the breast. It is typically non-invasive, which means it has not spread to other areas of the breast or body.
  • Invasive ductal carcinoma (IDC): This type of breast cancer begins in the milk ducts of the breast and can spread to nearby tissues. It is the most common type of breast cancer, accounting for about 80% of all cases.
  • Invasive lobular carcinoma (ILC): This type of breast cancer begins in the milk-producing glands of the breast and can spread to other areas of the body. It accounts for about 10-15% of all cases.

Other less common types of breast cancer include:

  • Inflammatory breast cancer (IBC): This is a rare and aggressive form of breast cancer that often causes the breast to appear red and swollen.
  • Paget’s disease of the nipple: This form of breast cancer starts in the ducts of the nipple and can spread to the areola (the dark area around the nipple).
  • Phyllodes tumors: These are rare tumors that develop in the breast’s connective tissue. They can be either benign or malignant.

Each type of breast cancer will require a distinct treatment approach, and it is crucial for those diagnosed with breast cancer to work closely with a team of healthcare professionals to determine the best course of action.

Type of Breast Cancer Location in Breast Percentage of Cases
Ductal carcinoma in situ (DCIS) Milk ducts 20%
Invasive ductal carcinoma (IDC) Milk ducts 80%
Invasive lobular carcinoma (ILC) Milk-producing glands 10-15%

Knowing the different types of breast cancer and their characteristics can help individuals take charge of their breast health and make educated decisions about their treatment options.

Importance of Early Detection in Cancer

Early detection is crucial in cancer treatment, and it can significantly improve the chances of survival. It is essential to understand the warning signs and symptoms of cancer, including lumps or masses in the body, to detect cancer early and increase the effectiveness of treatment. Lumps in the armpits are one such warning sign that may indicate cancer.

When you feel a lump in your armpit, it can be overwhelming and frightening. However, not all lumps are cancerous, and it is essential to get a proper diagnosis from your doctor or healthcare provider. Knowing what a cancer lump feels like can help you identify if you need further medical attention.

  • Cancer lumps are often hard and may feel immobile.
  • They can feel irregular or uneven on the surface and may be fixed to the surrounding tissue and skin.
  • They may or may not cause pain.

If you notice any of these symptoms, it is necessary to schedule an appointment with your doctor or healthcare provider promptly.

Early detection can help improve your chances of survival because cancer is easier to treat when it is in its early stages. Regular screenings or self-examinations can assist in the early detection of cancer and reduce the overall risks. For instance, mammograms can detect breast cancer in its early stages, while colonoscopies can detect signs of colon cancer early on. Therefore, it is crucial to consult a doctor or healthcare provider about the appropriate screening tests for your age, risk factors, and personal and family medical history.

Type of Cancer Recommended Screening Tests
Breast cancer Mammogram, ultrasound, MRI, or clinical breast exam
Colon and rectal cancer Colonoscopy, fecal occult blood test, sigmoidoscopy, or virtual colonoscopy
Lung cancer Low-dose computed tomography (LDCT)
Cervical cancer Pap smear or HPV test
Prostate cancer Digital rectal exam (DRE) and prostate-specific antigen (PSA) test

It is vital to understand that early detection does not always guarantee a cure; however, it can help improve the chances of successful treatment and increase survival rates. Therefore, it is crucial to focus on early detection, prevention, and follow-up care with your doctor or healthcare provider.

Treatment options for breast cancer

When it comes to breast cancer, early detection and prompt treatment are key. The treatment options for breast cancer depend on a variety of factors, such as the stage and type of cancer, the patient’s age and health condition, and the patient’s personal preferences. Some common treatment options are:

  • Surgery
  • Radiation therapy
  • Chemotherapy
  • Hormonal therapy

Surgery is often the first line of treatment for breast cancer. The goal of surgery is to remove the cancerous tumor and surrounding tissue. Depending on the size and location of the tumor, different types of surgery may be recommended, including:

  • Lumpectomy – Removes only the tumor and a small amount of surrounding tissue.
  • Mastectomy – Removes the entire breast.
  • Reconstruction – Reconstructs the breast after mastectomy.

After surgery, radiation therapy may be recommended to destroy any remaining cancer cells. Radiation therapy involves high-energy radiation beams targeted at the affected area. It is usually administered over the course of several weeks.

In some cases, chemotherapy may be used to kill cancer cells that have spread beyond the breast. Chemotherapy involves drugs that are administered either intravenously or orally. Hormonal therapy may also be recommended if the cancer is hormone receptor-positive. Hormonal therapy involves drugs that block the effects of hormones that can stimulate the growth of cancer cells.

It’s important to note that each patient’s treatment plan will be tailored to their individual needs and preferences. Patients should discuss their treatment options with their healthcare provider to determine the best course of action for them.

Treatment Option Pros Cons
Surgery – Can remove entire tumor and reduce risk of recurrence
– Can provide a definitive diagnosis
– May affect the appearance of the breast
– Can result in some loss of sensation in the breast or arm
– May require follow-up surgery for reconstruction
Radiation therapy – Can destroy any remaining cancer cells after surgery
– Can reduce risk of recurrence
– May cause fatigue, skin irritation, or other side effects
Chemotherapy – Can kill cancer cells throughout the body
– Can reduce risk of recurrence
– Can cause significant side effects such as nausea and hair loss
– May weaken the immune system
Hormonal therapy – Can block the effects of hormones that can stimulate the growth of cancer cells
– Can reduce risk of recurrence
– May cause hot flashes, mood swings, and other side effects
– May not be effective for all types of breast cancer

As with any medical treatment, there are pros and cons to each option, and it’s important for patients to discuss these with their healthcare provider to make an informed decision on their treatment plan.

How to conduct a breast self-exam

A breast self-examination is a test that allows a woman to examine her breasts for any unusual changes, such as lumps or bumps. This examination helps identify changes that may indicate early signs of breast cancer. While the self-examination shouldn’t replace clinical breast exams or mammograms, it’s an essential tool every woman should consider using on a monthly basis to stay aware of any changes in their breast tissue.

  • Step 1: Look at your breasts in the mirror with your shoulders straight and your arms on your hips. Make sure to check for any visible changes, such as swelling, dimpling, or changes in the contour of your breasts.
  • Step 2: Raise your arms and look for the same changes as in step 1.
  • Step 3: While lying down, use your right hand to check the left breast and the left hand to check the right breast. Start at the nipple and move in circular motions, checking for any lumps or changes in breast tissue. You can use a firm, smooth touch with the first few fingers of your hand or use a lotion to make the process smoother.

You should also make note of any discharge that comes from your nipples. If you notice any of the following signs, contact your healthcare provider:

  • Discharge (clear or bloody)
  • Lumps and thickening
  • Swelling or redness
  • Dimpling or puckering
  • New pain that is not related to your menstrual cycle

It’s important to perform self-examinations regularly, so you can familiarize yourself with your breast tissue and note any changes. Understanding what’s normal for you can help you detect any abnormalities early and seek medical attention promptly.

The frequency

Most healthcare providers recommend that women over 20 years of age do regular self-examinations at least once a month, to ensure that any changes can be detected early. However, younger women may be encouraged to do more frequent checks, as they may be more at risk.


A breast self-examination is an essential tool for women to use to take an active role in breast health and detect changes related to potential breast cancer early. Being familiar with your breast tissue and conducting regular self-examinations can go a long way in ensuring your overall health. Pairing self-examinations with regular clinical exams and mammograms can detect breast cancer early, which significantly increases the possibility of successful treatment.

Remember, the earlier breast cancer is detected, the better the chances of survival. Therefore, paying attention to your breast health is an absolute must, and self-examination is the first step towards it.
