Exercises to Do After a Mastectomy, According to PTs

Recovering from a mastectomy is no easy feat. The procedure itself involves the removal of an entire breast (sometimes both breasts), and healing time can range from three to six weeks, per the Memorial Sloan Kettering Cancer Center. During recovery, it’s not uncommon to experience a host of different sensations in your arm(s), breast(s), and chest, including tenderness and numbness. Pain, tightness, and swelling are also common, says Kelly Sturm, PT, DPT, CLT-LANA. Because of the attachment between the chest muscles and the shoulders, if a proper recovery plan isn’t created and executed properly post-surgery, shoulder dysfunction or rotator cuff injuries could also occur. Thankfully, there are some exercises that can help minimize injury and support muscle recovery.

“Stretching is the most important exercise after a surgery to maximize the muscle health and length,” Sturm says. “Tightness can lead to shoulder issues, back pain, neck pain, and more.” After a mastectomy, you won’t be able to jump right back into any kind of intense upper body routine or full body workout. But certain exercises can help your muscles recover post-surgery. To find out more, we asked oncology physical therapists about some of the best exercises to do after a mastectomy.

Why Should You Exercise After a Mastectomy?

Exercising after a mastectomy can help your body recover, but it’s important to start slow. “Stretching is the most important exercise after a surgery to maximize the muscle health and length,” Sturm says, noting that excessive tightness can lead to shoulder issues, as well as neck and back pain. Alexandra Hill, PT, DPT, OnCS, CLT-LANA, adds that shoulder strength and range of motion are both significantly reduced in the early days of post-mastectomy recovery, so gentle exercises are crucial to get the muscles working again. That said, “patients should work with a cancer rehabilitation specialist in their area to determine the most appropriate exercise plan to address their specific side effects [and] impairments,” says Elise K. Cantu.

What Causes Chest Tightness Post-Mastectomy?

Tightness after a mastectomy could be caused by several changes to the body, including shortening of the chest muscles, new inflammation and scar tissue, or the impact of breast reconstruction on the muscles, experts say. That’s why Sturm recommends following your surgeon’s instructions closely when it comes to the type of exercises you are able to do in order to avoid causing injury to the area. Once you’re cleared by your surgeon, Sturm recommends light exercises to improve shoulder range of motion and chest stretches to help with tightness and pain.

Exercises to Do After a Mastectomy

“Exercises that focus on improving mobility and flexibility of the shoulders and chest are key,” Hill says. “These mobility exercises will help with muscle tightness as well as improve scar mobility, decrease pain, and help you get back to your full range of motion for daily activities.” Here are five mobility exercises that meet that criteria, plus video instruction from Sturm. These can be done two to three times per day to help with recovery. As a note, always check with your own medical team to determine the best recovery plan for you, and remember that every person’s recovery looks a little different.

How to Work These Mobility Moves into Your Recovery Routine

Most surgeons want their patients to avoid significant exercise until surgical drains are removed. That said, “once cleared, gentle stretches or exercises done one to two times a day for a few weeks can help with recovery,” Sturm says.

“Healing after a mastectomy can take up to six to eight weeks depending on the type of mastectomy,” Hill adds. “It’s important to continue with mobility exercises two to three times per day at least through this time period of six to 12 weeks as the tissues continue to heal.” As you work through mobility movements as your body starts to heal, be mindful of any extreme discomfort. If you experience increasing pain, sudden or severe shortness of breath, or dizziness, or your body feels “off,” you should discontinue your exercise session, Cantu says.
