Stages من إعداد فريق مايو كلينك Ductal carcinoma in situ (DCIS) is a stage 0 breast cancer. The stage is a way to describe the size of the cancer and whether it has spread. Breast cancer stages range from 0 to 4. A lower number means the cancer is less advanced and more likely to be cured. As the cancer grows into the breast tissue and gets more advanced, the stages get higher. Stage 0. When DCIS occurs on its own, it's a stage 0 breast cancer. This means the cancer is found inside a duct and shows no signs of growing into nearby tissue. Stages 1, 2, 3 and 4. Stages 1 through 4 are used for invasive breast cancers. If an area of DCIS is found along with invasive cancer, it's considered an invasive cancer. This includes very small areas of invasive cancer, called microinvasions. Sometimes tests suggest that the cancer is DCIS, but surgery shows that it is invasive breast cancer. Because of this, the stage might not be known until after surgery. طلب تحديد موعد التشخيص والعلاج 07/11/2024 تبادلها عبر ارسلها على الفيس بوكارسلها في تغريدة Living with سرطان القنوات الموضعي (DCIS)?
