Of the 6% of recurrence of breast cancer cases, about 90% of the relapse is because of the positive margin. Positive margin is an area adjacent to the location where the cancerous tissue was removed. Therefore, preventing positive margin will make a big difference in recurrence of breast cancer.
A recent study titled “A Randomized, Controlled Trial of Cavity Shave Margins in Breast Cancer”, published on the New England Journal of Medicine, suggests that removing a little extra tissue during the initial surgery to remove cancerous tissue may reduce the chance of recurrence and thus reducing a second operation by 50% . When surgery is performed, the best result arises when all the cancerous tissue is removed. This is one reason why mastectomy is performed; by removing the entire breast, the risk of relapse is decreased. After a lumpectomy is performed, in some cases, unremoved healthy-looking tissue can turn out to be a cancerous tissue. To prevent the chance of leaving cancerous tissue, removing additional tissue during surgery may likely reduce the chance of relapse.
Women often think taking extra tissue away will affect the cosmetic effect by reducing the size of their breast. However, interestingly, the study concluded that even though more tissue is, patients that had extra tissue removed had the same perception of cosmetic outcome as patients without shaving the extra layer.
Reducing the risk of recurrence of breast cancer is vitally important, however, according to the National Cancer Institute, the early detection of breast cancer is more crucial as the survival rate for women is more than 98% when breast cancer is detected and treated before the cancer metastasis. UBCF offers a variety of programs to serve women, men and families affected by breast cancer. UBCF’s Breast Screening program provides women and men free or low-cost breast screenings and information about self-breast exams. UBCF further assists women with breast reconstructive surgery, helping women feel whole, and empowered to move forward with their lives.
6%의 유방암 재발중 90%는 positive margin때문에 재발합니다. Positive margin이란, 첫번째 유방암 수술이 이루어졌을때 암이 제거된 구역 근처의 미처 제거되지못한 암세포들을 말합니다. 그러므로, positive margin은 유방암 재발에 큰 역할을 합니다.
New England Journal of Medicine에 소개된 최근연구에 따르면, 첫번째 유방암 수술이 행하여질때 이전에 행하여졌던 유방암수술보다 조금더 제거하면, 유방암 재발의 가능성이 50% 줄어든다고 합니다. 유방암수술을 할때 가장 중요한 점은 모든 암세포를 제거하는것인데요. 유방절제술(Mastectomy)이 행해지는 이유입니다. 한쪽 또는 두 쪽 모두의 유방을 절제하기 때문에 재발의 가능성이 줄어드는 것입니다. 하지만 유방 종양 절제술(lumpectomy)가 행하여지면, 종종 제거되지않은 일반세포처럼보이던 암세포들이 활동을하게될 수도 있습니다. 따라서 암세포로 변이될 가능성이 있는 일반 세포를 미리제거함으로서 extensive breast cancer surgery는 유방암재발의 위험성을 낮추게 됩니다.
여성분들은 미적인 이유때문에 종종 유방을 조금더 절제하는것에 부정적인 의견을 보이는 경우가있습니다. 하지만, 연구에따르면 유방을 조금 더 절제할 지라도, 환자의 미적 지각은 달라지지 않았습니다.
유방암 재발을 막는것은 중요합니다. 하지만, National Cancer Institute에 따르면, 유방암을 조기에 발견하는것이 매우 중요하다고 합니다. 실제로 암이 전이되기전에 발견한 환자의 98%가 살았다고합니다. UBCF에서는 다양한프로그램은 여성뿐만아니라 남성과 환자의 가족들에게 까지 제공하고 있습니다. UBCF의 Breast Screening program은 여성과 남성에게 공짜또는 저가의 breast screening 프로그램을 운영하고있고, 또한 자가진단법을 알려드리고 있습니다. 또한UBCF는 여성들에게 유방복원수술을 지원함으로써 여성분들을 밝은 미래로 인도하고 있습니다.
