While recovering from breast cancer surgery — whether a mastectomy, lumpectomy, or reconstructive surgery — some discomfort is normal. Chest tightness after breast surgery can be a persistent symptom due to a variety of factors. It could be linked to neuropathic pain, scar tissue or soft tissue restriction, radiation-related fibrosis, or musculoskeletal contributors, among others.

Fortunately, there are ways to manage this uncomfortable condition, which is called postmastectomy pain syndrome (PMPS) or “iron bra syndrome.”

One MyBCTeam member shared that they learned about PMPS years after their unilateral mastectomy: “I never realized the inability to tolerate anything tight around my chest had a name. Perfect simile — iron bra is exactly what it feels like!”

Another member described symptoms that can appear at certain times: “My biggest issue is that when I feel that I am catching a cold, the area from my sternum all the way past my scapula, near my spine, is greatly affected. The area sometimes feels like I have an inflated balloon under my arm, while at other times I feel as if there’s barbed wire there that someone’s twisting.”

In this article, we explore six ways to address PMPS at home, along with tips on when to see a doctor to manage your discomfort. Always speak to a healthcare professional before starting any new therapies, treatments, or exercise routines, especially while recovering from breast cancer surgery.

1. Enlist a Physical Therapist

When you’re working to address soreness, tightness, and pain in your chest wall after breast cancer surgery, consider meeting with a physical therapist or physiatrist (rehabilitation doctor). Speak to your surgeon for a referral to a therapist who understands iron bra syndrome and has worked with people after breast cancer surgery.

Under a therapist’s supervision, you can create an exercise routine that will help reduce tightness and increase your range of motion without pushing yourself too hard. The exercises you do might change over time as you go through the healing process. But it’s important to start early while scar tissue is still forming.

Even when you aren’t physically in the physical therapy (PT) clinic, you can do exercises at home. One member shared, “I do the PT arm exercises and lymphedema exercises two to three times a day, and lift light weights.”

Seeing a physical therapist can help lead you in the right direction on your path to PMPS recovery.

2. Ease Tightness With At-Home Stretches

One cause of iron bra syndrome is a lack of mobility in the pectoral (chest) muscles and surrounding areas. When you have a tight muscle, it’s important to stretch carefully to reduce the tightness.

“I do a dozen other stretches,” one MyBCTeam member said. “Because I have so many different tight areas in my body, I try to combine stretches.”

Stretching is helpful not just for your chest muscles, but also for your arms, back, hips, and other body parts. The American Cancer Society provides instructions for some stretches to try after breast cancer surgery. Adding daily stretching to your routine may help reduce chest tightness and begin to combat PMPS.

3. Build Muscle and Strong Bones With Strengthening Exercises

Disruption of the pectoral muscles can also cause chest tightness after breast cancer surgery and breast reconstruction. This is why some members, long after their surgeries, turn to weightlifting and other strengthening exercises after getting their surgeon’s OK.

One MyBCTeam member shared, “I am hoping that strengthening exercises help me rebuild whatever muscle I have left. I started easy with the 15-pound bar; I did chest presses, tricep presses, lunges, rows, bicep curls, overhead press, and weighted squats. I want to work up to eventually going back to the gym and using bars and barbells.”

If you are new to weightlifting, you may benefit from having a personal trainer on your recovery team. “I started meeting with a personal trainer at the gym (a six-month membership was paid by my oncologist’s office),” another member said. “I also found a great core class at that gym with an awesome trainer, and that has helped me tremendously.”

Weightlifting not only builds up weak muscles. It also strengthens your bone health and reduces your risk for osteoporosis (decrease in bone density and mass).

There are many ways to begin weightlifting, whether you’re a beginner or a veteran who had to take a break due to surgery.

Follow Your Medical Team’s Guidance

When starting intense physical activity after surgery, it’s important to proceed with caution. Return-to-activity timelines vary widely based on your type of surgery, reconstruction level, drain removal status, wound healing, and any possible complications.

Following your surgical team’s specific plan is critical to making a full recovery. Once you have their approval, you can work your way up from lighter to heavier weights.

4. Hit the Pool for a Low-Impact, Full-Body Workout

If resistance training isn’t your thing or your surgeon hasn’t approved weightlifting, swimming maybe a good option for you. Water exercises can increase mobility, strengthen muscles, help manage fatigue and pain, and improve cardiovascular fitness.

Water exercises can ultimately help reduce some of the discomfort linked with iron bra syndrome through a low-impact workout. “I found swimming, especially breaststroke (ha ha ha), really helpful,” one member shared.

Before you begin swimming, make sure your incision sites have completely healed to prevent the risk of an infection. Only swim once your incisions are fully healed, drains are out (if applicable), and the surgeon clears it.

Consult your healthcare team before you begin adding swimming or other water exercises to your healing routine.

5. Wear Comfortable Clothing

When you’ve got iron bra syndrome, wearing uncomfortable undergarments is the last thing you want to do. Members often discuss what kinds of bras are most comfortable to wear after breast cancer surgery.

One member said, “I can’t wear anything that has any tightness around where a bra would lay, especially below the breast. I’ll go up a size and hope maybe that will give me less of a tight feeling.”

This means avoiding garments that make your chest tightness even more unbearable. These may include underwire bras, tight sports bras, bathing suits, and shirts with built-in shelf bras.

Another member said, “I wear bralettes without any discomfort.”

On top of a good exercise regimen, keeping yourself comfortable with good-quality bras can help you manage chest tightness.

6. Seek a Medical Opinion

Contact your doctor immediately if you have symptoms such as:

• Fever
• Headache
• Increasing skin discoloration or warmth
• Drainage
• Rapidly worsening swelling
• New shortness of breath
• Sudden or worsening chest pain

Your doctor can make sure you’re recovering normally from surgery, radiation therapy, and/or chemotherapy.

Persistent or worsening symptoms require medical evaluation to make sure you’re not dealing with something more serious than PMPS. There are a variety of possible side effects after surgery. Your doctor can help rule out other potential causes of your pain with imaging or other testing.

If you need additional pain relief, they may recommend medical treatments such as pain medications, nerve blocks to treat nerve damage, or other medications and procedures.
