Dataset Cancer

Breast cancer is a disease in which cells in the breast grow out of control. There are different kinds of breast cancer. The kind of breast cancer depends on which cells in the breast turn into cancer. Breast cancer can begin in different parts of the breast. A breast is made up of three main parts: lobules, ducts, and connective tissue. The lobules are the glands that produce milk. The ducts are tubes that carry milk to the nipple. The connective tissue (which consists of fibrous and fatty tissue) surrounds and holds everything together. Most breast cancers begin in the ducts or lobules. Breast cancer can spread outside the breast through blood vessels and lymph vessels. When breast cancer spreads to other parts of the body, it is said to have metastasized.乳腺癌是一种乳腺细胞失控性增殖的疾病。乳腺癌存在多种分型，其分型取决于发生癌变的乳腺细胞类型。乳腺癌可始发于乳腺的不同部位。乳腺主要由三个部分构成：乳腺小叶、乳腺导管以及结缔组织。乳腺小叶为分泌乳汁的腺体；乳腺导管是将乳汁输送至乳头的管状结构；结缔组织由纤维组织与脂肪组织构成，可包裹并固定各组织结构。多数乳腺癌始发于乳腺导管或乳腺小叶。乳腺癌可通过血管与淋巴管扩散至乳腺外区域；当癌细胞扩散至身体其他部位时，即发生了癌转移。
