Does breast reduction increase cancer risk?

Concerns about whether this surgery could increase the risk of breast cancer have been a topic of interest.
Most studies indicate that breast reduction surgery does not increase the risk of breast cancer. In fact, some research suggests that it might even reduce the risk, as the surgery removes a significant amount of breast tissue, potentially decreasing the chances of cancer developing in that tissue.
There is a possibility that during the surgery, previously undetected cancerous cells might be found.
It's important for women who have undergone breast reduction to continue regular breast cancer screenings. The surgery can change the appearance and feel of the breasts, which might make self-exams or mammograms slightly different, but not less effective.
The overall risk of breast cancer is influenced more by factors such as genetics, family history, age, and lifestyle rather than breast reduction surgery itself.
In summary, current evidence suggests that breast reduction surgery does not increase the risk of breast cancer and may actually reduce it in some cases. Regular screenings and consultations with healthcare professionals remain crucial.

Breast reduction surgery decreases breast cancer risk. The aim of this surgery is reducing the amount of breast tissue. Smaller tissue means less risk

Breast reduction surgery does not increase the risk of developing breast cancer. In fact, it may potentially improve breast health by making it easier to detect any abnormalities through better imaging and self-exams. The procedure involves removing excess breast tissue, which can reduce breast density. Lower breast density can make mammograms and other imaging tools more effective in identifying tumors, allowing for earlier detection of cancer. Although breast reduction is not a preventive measure against cancer, it can assist in identifying potential risks earlier, helping to detect tumors at a more treatable stage.
That being said, there are various factors that contribute to breast cancer risk, and breast reduction surgery does not alter those risk factors. If you have a family history of breast cancer, certain genetic mutations (like BRCA1/2), or a previous diagnosis of breast cancer, your risk may be higher. Other risk factors include prior radiation therapy to the chest. While a breast reduction does not eliminate these risks, it can enhance the effectiveness of breast cancer screenings, allowing for more accurate detection due to the reduced breast tissue density.
In addition to improving breast health and making early detection easier, breast reduction can offer significant benefits to your overall quality of life. Many women experience relief from chronic pain in the neck, shoulders, and back caused by large breasts. It can also help alleviate skin issues and reduce shoulder grooving from bra straps. While breast reduction does not directly reduce cancer risk, it can improve comfort and well-being. Regular breast cancer screenings, such as mammograms and ultrasounds, remain essential for individuals who have undergone any form of breast surgery to monitor for potential abnormalities. If you are concerned about your cancer risk, discuss your options with a healthcare provider to determine the best course of action for your situation.
