The truth about sports injuries: Can they increase your risk of breast cancer?

There are many myths circulating around this topic!

If you had an active childhood spent playing sports afterschool or on the weekend you might have sustained the odd sports injury here and there in those rough and tumble days. Let’s face it, netball can get a bit rough and elbows tend to go flying at the best of times. Sometimes our old injuries can come back to haunt us as we age.

Some people believe that sports injuries can lead to breast cancer, however, it is important to understand that this is not the case. There is no link between sports injuries and cancer however an injury may draw attention to a previously formed lump, which is then how the cancer is detected.

Breast trauma causes lumps

People are understandably concerned that breast injury/trauma can cause cancer because the trauma can cause lumps to develop. These lumps, however, are not cancerous. Let me explain further: there are two types of lumps that can develop from trauma. The first is called hematoma and this is a deep bruise that will heal. The other is fat necrosis, which is scarred fatty tissue in the breast that results from injury.

If you have had some sports injury around the breast area, and you are concerned, the best thing to do is to book in for a mammogram. This will give you peace of mind about the risks.

So what does cause breast cancer?

There are certain risk factors that you cannot change, for example getting older or having a family history of breast cancer or ovarian cancer. Other risk factors include previous treatment using radiation therapy, your reproductive history and genetic mutations.

Factors that can help you avoid breast cancer

We must all try our best to keep physically active and to keep our weight in the healthy range. Your diet should contain a large variety of fruits and vegetables and lean protein. It’s also advisable to limit your alcohol intake and not to smoke.

Stress is also a big factor that places unnecessary pressure on our body.  At a cellular level, it is important that we support our body with an active lifestyle, quality sleep and activities to reduce stress.

When it comes to breastfeeding, research shows that the risk of breast cancer is reduced by 4.3 percent for every 12 months of breastfeeding, this is in addition to the seven percent decrease in risk observed for each birth. Breastfeeding reduces the risk of Triple‐Negative Breast Cancer by 20 percent and in carriers of BRCA1 mutations.

When it comes to oral contraception, research studies provide consistent evidence that the risks of breast and cervical cancers are increased in women who use oral contraceptives, whereas the risks of endometrial, ovarian, and colorectal cancers are reduced.  Having said this, the risks for breast and cervical cancers are extremely low and it is important to take into account other factors such as family history.

Screening for breast cancer

A woman’s risk of developing breast cancer increases with age. Over 75 percent of breast cancers fall into the 50 to 74 years age group. Regular breast screens are the best way to find cancer early. If you are in this age group, you can have a free mammogram every two years. If you’re outside of this age range, it is still important to be vigilant, undertake self-examinations, undertake regular screening and speak to your doctor if you have any concerns or symptoms.

Tips for self examinations

Associate Professor Warrier’s easy system to help women undertake self-examinations at home called ‘LOOK, LIFT, FEEL’ is the ideal way to check for lumps or other issues.

LOOK, LIFT, FEEL only takes a few minutes and should be done regularly.  Look at your breasts in the mirror to identify any changes in shape, colour or texture.  Then lay flat and lift your arm up over your head and with two fingers together, using the pads of each finger, place gentle pressure on the breast moving your fingers around in a circular motion.  Change sides and repeat.

Take your time and feel for any lumps or changes in the breast.  Remember that your breasts may be dense and will naturally feel uneven.  If you encounter any changes or unusual lumps, book an appointment with your doctor.  The majority of issues are benign, but it is always important to check things with your doctor.
