Breast Cancer's Relationship Toll

For many women, the diagnosis of breast cancer represents not only a major physical battle, but also the ultimate emotional challenge -- one that affects every relationship in our life. Indeed, from friendships to romance, from being a parent to being a daughter, the way you relate to everyone -- and the way they relate to you -- can be affected. "I do think cancer has more impact on emotions and emotional relationships than other catastrophic diseases, because with cancer, death is often the...

  • Infection.
  • Hematoma .A build-up of blood under your skin
  • Seroma. A build-up of fluid under your skin
  • Lymphedema . Swelling in the arm
  • A bad reaction to anesthesia

Talk to your doctor about all these possibilities before you have your surgery. The medical staff will keep an eye out for problems while you're in the hospital. Once you’re home, you’ll need to know the symptoms of problems:

Infection. Look for redness or swelling of the incision with pus or foul-smelling drainage. You may have a fever. Usually, antibiotics can treat these infections.

Lymphedema. Look for swelling of the arm or hand on the side of the surgery. This happens to some women after the lymph nodes under the arm are removed. It may go away on its own, but you may need to see a physical or occupational therapist. Treatments may include:

  • Draining the fluid
  • Compression bandages to keep the swelling down
  • Skin care
  • Arm exercises

Seroma. You may notice swelling from a build-up of fluid at the site of the surgery. Usually, fluid is absorbed by the body. If it doesn’t go down on its own, your doctor may need to drain the area, using a needle.

If you notice any of these symptoms, let your doctor know right away.

You may have pain and stiffness in your shoulder as you recover. You may also have numbness or unusual sensations in the upper arm or armpit. Usually these side-effects go away with time.

Complications of Reconstructive Surgery

Many women opt to get their breast reconstructed right after their cancer is removed. Problems can stem from that operation, too. They include:

  • Infection
  • Poor healing
  • A leak or rupture of your breast implant
  • Scar tissue around your implant

Before any surgery, your doctor should give you information about the procedure, recovery, and follow-up care. Read it over, and get all your questions answered beforehand.

When you understand the surgery and the possible complications, you’ll be better able to care for yourself and catch problems early on.
