Location of Breast Cancer Does Matter

Location of Breast Cancer Does Matter
Does it really matter which part of the breast you develop cancer? Researchers say yes.
Researchers from Switzerland recently reported that women with early breast cancer in the lower inner quadrant (the lower part of the breast, closer to the center of the body) are twice as likely to die of their cancer as women with cancer diagnosed in other parts of the breast. Researchers speculate this could be due to undetected spread of the cancer to the lymph nodes of the internal mammary chain (lymph nodes near the center of the chest). These lymph nodes are difficult to be evaluated for the presence of cancer.

These researchers analyzed information about 1411 women with stage I breast cancer diagnosed between 1986 and 2002. In addition to tumor location, researchers collected information about patient age, tumor size, and whether or not the woman received chemotherapy.

By 10 years after diagnosis, 93% of the women were still alive. Women whose tumors were located in the lower inner quadrant of the breast had twice the mortality rate (11%) of women whose tumors were located in other parts of the breast. The risk of death among women with tumors in the lower inner quadrant of the breast remained significantly higher, even among those who underwent chemotherapy.

The researchers suggest that the higher risk of death among women with tumors in the lower inner quadrant of the breast may be due to mistaken lower staging (underestimation of the extent of the cancer), leading to under-treatment. They recommend that women with tumors in the lower inner quadrant of the breast undergo sampling of the lymph nodes of the internal mammary chain.
