What is BSE and why do them?

BSE is a simple and effective way to recognize the early signs and symptoms of breast cancer. Breast cancer the second most common form of cancer in cis women (nonmelanoma skin cancer is the most common) and has the second highest cancer mortality rate among cis women (lung cancer has the highest rate). Approximately 200,000 people in the U.S. will be diagnosed with breast cancer and 40,000 will die from the disease each year. BSE is the first line of defense to detect breast cancer at an early stage and increase the chances for a successful recovery. 

When should I perform BSE and how often?

BSE should be performed once a month. The procedure itself is simple and only takse a few minutes. The best time to do a BSE is about a week after your period because you may experience breast tenderness and bloating before and during your period. If you are taking birth control pills, the week you start a new pack can remind you to perform a BSE.

If you don't have regular periods, it may help you to remember to do BSEs if you choose a date each month that's easy to remember like your birth date or the first of each month. Performing BSEs on a regular basis will allow you to become familiar with the size and feeling of your breasts and can help you detect any changes if they occur.

In addition to BSEs, after the age of 20 you should schedule a regular clinical breast exam with your medical provider every year. 

How do I perform BSE and what am I looking for?

BSE is simple to perform and can quickly become a part of your health routine. You can also ask a partner if they would perform BSE for you.

  1. Look in the mirror at your breasts. Put your hands on your hips and bend slightly forward from the waist. Look for any signs of dimpling, puckering, or uneven textures in both breasts. Look again with your arms raised above your head.

  2. Standing in the shower, you can use soap to allow your fingers to slide more easily over your skin. With your right hand behind your head, use your left hand to check your right breast. Using the flat pads of your fingers, start at the upper corner of your breast (closest to your armpit), and with firm pressure move your fingers together in a circular motion. Slowly move your fingers in one of 3 ways: a circular pattern around the breast moving in towards the nipple; a vertical up and down motion from armpit to rib cage; or a diagonal wedge motion from the edge of the breast to the nipple and out again. Be sure to cover the entire breast and underarm area and use the same method each month. To view a picture of these methods, you can visit The Susan G. Komen Breast Cancer Foundation's site to view or download a BSE instruction card.

  3. Switch sides by placing your left hand behind your head and use your right hand to check your left breast.

  4. Squeeze both nipples to check for signs of discharge (other than breast milk).

  5. Repeat the process lying down. Sometimes it can be easier to recognize lumps when the breast tissue is flat against your chest.

When performing BSEs you are looking for:

  • Any dimpling or puckering of the skin

  • Changes in the nipple: inverted, scaliness, discolored, or discharge

  • Redness

  • Swelling

  • Warmth in the breast

  • Skin that appears pink, reddish purple or bruised

  • Skin that has ridges or appears pitted, like the skin of an orange.

  • Pain in the breast

  • A mass that is painless, hard and has irregular edges

If you have any of these symptoms and you are a Brown student, call 401.863-3953 to make an appointment at Health Services to have a medical provider do a clinical breast exam. You can request a specific provider by name or by gender. 

What does it mean if I find a lump?

It is important to remember that breast changes are normal, especially in young people. Just because you find a lump or notice a change in your breasts doesn't mean that you have breast cancer. Some people have lumpy breasts and others experience regular breast changes during their menstrual cycle. If you are concerned about a lump, have your medical provider perform a clinical breast exam to determine whether you need further testing, such as a mammogram, ultrasound or biopsy. These tests will help determine if the lump is cancerous or if the lump is actually a cyst, a symptom of nodular sensitive breasts or another benign (not cancerous) breast condition. Out of the lumps that are biopsied, 80% are found to be benign. However, if you do notice a lump, enlargement, tenderness or other unexplained changes in your breasts, talk to your medical provider right away. The sooner you have the lump diagnosed, the more treatment options you will have and the more successful your treatment will be.

What are the risk factors for breast cancer?

There are different types of risk factors for breast cancer. Some risk factors are inherent - you can't change them. Other risk factors are related to lifestyle choices and can be changed. Some factors can put you at higher risk than others and risk factors can change over time. Some of the risk factors that cannot be changed include:

  • Biological sex - being a person assigned female at birth is the main risk factor for developing breast cancer.

  • Age - your risk of developing breast cancer increases as you get older.

  • Genetics - 10% of breast cancer cases are hereditary as a result of gene changes (mutations).

  • Family History - breast cancer risk is higher among people whose close blood relatives have this disease.

  • Personal History - someone with cancer in one breast has a 3- to 4-fold increased risk of developing a new cancer in the other breast or in another part of the same breast.

  • Race - White women are slightly more likely to develop breast cancer than are African-American women. Asian, Latino, and Native American women have the lowest risk of developing breast cancer.

  • Previous Biopsies - people whose earlier breast biopsies detected proliferative breast disease are at higher risk.

  • Previous Irradiation - people who as children or young adults have had radiation therapy to the chest area as treatment for another cancer (such as Hodgkin's disease or non-Hodgkin's lymphoma) have a significantly increased risk for breast cancer.

  • Menstrual History - people who started menstruating at an early age (before age 12) or who went through menopause at a late age (after age 50) have a slightly higher risk of breast cancer.

Risk factors that are related to lifestyle choices that can possibly be changed include:

  • Not having children - people who have not had children or who had their first child after age 30 have a slightly higher breast cancer risk.

  • Oral contraceptive use - studies have found that oral contraceptive users may have a slightly greater risk of breast cancer than those not using them, although the level of risk is still not clear.

  • Hormone replacement therapy - most studies suggest that long-term use (5 years or more) of hormone replacement therapy (HRT) after menopause will increase your risk of breast cancer.

  • Not breast-feeding - many studies have shown that breast feeding lowers breast cancer risk.

  • Alcohol consumption - if you drink 2 to 5 alcoholic beverages a day it can increase the risk of developing breast cancer to 1.5 times the risk of non-drinkers.

  • Obesity and high-fat diets - being overweight is associated with an increased risk of developing breast cancer, especially after menopause.

    (Adapted from American Cancer Society, "What are the risk factors for breast cancer.")

It is important to remember that just because you have one or more risk factors does not guarantee that you will develop breast cancer. Some people with a number of risk factors never develop breast cancer while the majority of people with breast cancer have no identifiable risk factors. 

What are mammograms?

A mammogram is a screening procedure that uses x-ray photographs to look deep into the breast tissue. Mammograms can detect a lump well before it can be felt. The process involves a mildly uncomfortable squeezing of the breast between 2 plastic plates in a x-ray machine. The procedure should not be painful and only lasts a few minutes. Annual mammograms are recommended for cis women over the age of 50. It is recommended that cis women between the ages of 40 and 50 have a mammogram every 2 years, and depending on their medical history, younger people may also decide to have mammograms. 

Can people of any gender get breast cancer?

Yes, people of all genders can also develop breast cancer, although the incidence of breast cancer among cis men is low. Approximately 1,500 cis men will be diagnosed with breast cancer and 400 will die from the disease each year in the U.S. 

Does having breast implants or breast reduction surgery increase the risk of breast cancer?

The National Cancer Institute conducted a study that followed over 13,000 people for over 10 years to examine whether there is an association between having breast implants and having an increased risk for breast cancer. The study found that there was no change in breast cancer risk for those who had breast implants. Click here to read more about the study.

If you have implants, you should still perform BSEs. In order to do this effectively, you should ask your medical provider to help you distinguish the implant from your breast tissue. Press firmly inward at the edges of the implants to feel the ribs beneath, checking for any lumps. However, be careful not to manipulate (e.g., squeeze) the implant excessively, which may cause the implant to leak or deflate. Any new lumps or sores should be evaluated with a biopsy. If a biopsy is performed, care must be taken to avoid puncturing the implant.

A research study published in the February 2001 issue of Cancer, found that people who had breast reduction surgery actually decreased their risk of breast cancer. However, breast reduction surgery is not recommended as a method to prevent breast cancer.
