Breast pain is sometimes associated with breast cancer, but it’s not a common symptom. Breast lumps and visual changes to the breasts or nipples are more typical signs.
While some people with breast cancer may experience breast pain, it’s not a typical sign or symptom of breast cancer. Treatment for breast cancer and any breast cancer that has spread from the breast may cause pain in other parts of the body.
This article discusses how and when breast cancer causes pain, common symptoms of breast cancer, and other reasons for breast pain.
Breast pain, also called mastalgia, is not a common symptom of breast cancer.
When breast pain is related to breast cancer:
Metastatic breast cancer — cancer that has spread to areas beyond the breast — can cause pain, depending on where it spreads.
Examples of this include:
Pain can sometimes be a side effect of breast cancer treatments such as:
The most common sign of breast cancer is a lump or mass in the breast. The lump is usually hard and painless. Other signs of breast cancer are:
Pain increases about 2 weeks before your period and begins to fade once you start. Hormone levels can also vary with puberty, pregnancy, and menopause.
Engorged breasts can feel hard and tight. And it’s not unusual to have sore or cracked nipples while breastfeeding. It may be helpful to speak with a lactation consultant or doctor if this is happening to you.
Mastitis is painful inflammation in the breast. Other symptoms include:
Because mastitis can involve infection, it’s important to seek medical help for treatment.
A breast abscess is a collection of pus due to infection. Other symptoms can include redness, swelling, and skin that’s warm to the touch.
Untreated infections can lead to serious complications, so it’s important to reach out to a doctor.
Gynecomastia can cause breast pain in males. It’s a condition in which the breasts enlarge, likely due to medications or hormonal changes. Gynecomastia can be treated, but it sometimes resolves on its own.
You might have breast pain due to a recent injury or surgery on or near the chest.
Breast pain can be a side effect of certain medications, such as:
Breast pain can also be referred pain. This is when pain originates somewhere else, such as the chest wall, gallbladder, or stomach, but you feel it in the breast.
Although an update to their guidelines is currently in progress, the 2016 screening recommendations from the U.S. Preventive Services Task Force are that women ages 50 to 74 with an average risk of breast cancer receive mammography screening every 2 years.
The recommendations also state that for women ages 40 to 49, mammography screening should be based on an individual decision. Earlier screening may be more beneficial to people with a higher-than-average risk.
American Cancer Society guidelines recommend:
If you have a higher risk of developing breast cancer, you may want to screen earlier or more often than recommended.
Breast cancer risk factors include:
It’s also helpful to be familiar with how your breasts normally look and feel so you can spot changes right away. One way to do this is by performing breast self-exams.
About 2–7% of people with breast cancer report pain as the primary symptom at the outset.
Inflammatory breast cancer is rare and presents differently than other types of breast cancer. There’s usually no lump, but it can be painful.
Other symptoms include:
Back pain is not typically associated with early-stage breast cancer but could be a symptom of metastatic breast cancer that has reached the bones. Of course, back pain can be due to many other conditions, including arthritis and muscle strain.
First, let your oncology team know that you’re in pain. It may help to keep a pain journal, noting where it occurs and how long it lasts.
Your healthcare team’s pain management strategy may include medications, physical therapy, and relaxation techniques.
In metastatic breast cancer, tumors can press on nerves and organs. In these cases, surgery or radiation therapy can remove or shrink tumors to relieve pain.
Breast cancer can cause breast pain, but it’s not common. Breast lumps and visual changes to the breast or nipple are more frequent signs of breast cancer.
Pain in other areas of the body can be a sign that breast cancer has spread. Pain can also be a side effect of breast cancer treatment.
If you have breast pain or other changes to your breasts, consider seeing a doctor. Without treatment, even benign breast conditions can lead to complications. And like all cancers, breast cancer is easier to treat in the earlier stages.
