There are plenty of misconceptions swirling around breast cancer, like people assuming that men can’t get the disease or that wearing a bra can cause it. But one of the biggest and potentially most harmful myths is that breast cancer can’t hurt.
That concept surfaced again late last week, after former Bachelorette star Katie Thurston revealed that she has breast cancer. The 34-year-old shared in an Instagram Story that she noticed she had a lump in her breast, but waited to have it evaluated by a doctor because it was painful. That pain “probably led to more doubt and delay on getting it checked out as most [websites] will say ‘most breast cancers don’t hurt,’” Thurston wrote. “I really thought it was PMS or working out,” she added.
Unfortunately, doctors who treat patients with breast cancer say this is a common misconception—and one that can lead to a delay in diagnosis and treatment. Here’s why and when breast cancer can hurt plus how to know when you should see a doctor for pain in your breast.
There are multiple reasons why breast cancer could hurt.
To be fair, yes, most women with undiagnosed breast cancer don’t have pain. “It is not common for breast pain to be associated with breast cancer. However, it still can happen,” Nicole Williams, MD, a breast medical oncologist with The Ohio State University Comprehensive Cancer Center – James Cancer Hospital, tells SELF.
But there are a handful of reasons why you might feel pain with breast cancer, and a lot of it boils down to the size of the tumor and where it’s located, Richard J. Bleicher, MD, chief of the division of breast surgery at Fox Chase Cancer Center, tells SELF. “If you have a breast cancer that’s very large, it can impinge on nerve structures, muscle structures, bone structures, and any component of the breast outside of the breast tissue—that can cause pain,” he says.
But even small tumors can lead to pain. “Breast cancers tend to be very hard,” Dr. Bleicher says. “Even if a lesion is small, it will cause discomfort if it is impinging on a nerve or muscle.”
Certain types of breast cancer are also more likely to be uncomfortable than others, Jason Mouabbi, MD, assistant professor in the department of breast medical oncology at The University of Texas MD Anderson Cancer Center, tells SELF. Inflammatory breast cancer, which accounts for up to 5% of all breast cancers, usually causes symptoms like redness, swelling, and a lot of pain in the breast, he points out. “But all breast cancers have the potential to cause pain,” Dr. Mouabbi says.
The myth that breast pain can’t be a sign of cancer is persistent.
The assumption that breast cancer won’t hurt is a “relatively fair one,” Dr. Bleicher says. The majority of the time, breast pain won’t be due to breast cancer, Katherine Cline, CNP, a breast cancer nurse practitioner with The Ohio State University Comprehensive Cancer Center – James Cancer Hospital, tells SELF. There are so many more likely reasons your breasts could hurt. “Breast pain is mostly caused by hormonal changes, certain medications, cysts/benign masses, or infections,” Cline says. Given that breast cancer is also painless more often than not, it’s easy to see how people might write it off completely as a potential explanation for this symptom.
