胆固醇，常常在肿瘤中积聚，可能改变脂肪细胞的细胞膜结构，从而产生影响肿瘤细胞生长和生存的生物信号。
Cholesterol, often stored in tumors, may change the structure of fatty cell membranes to produce signals that influence cancer cell growth and survival.
肿瘤细胞内糖原含量明显降低，但是有较多的脂肪滴。
Decreased glycogen and increased fat droplet were also present in the tumor cells.
葡萄糖和脂肪这样的营养物质越多，肿瘤细胞生长所需的物质来源就越多。
If you have more nutrients like glucose or fat then the cancer cells would have resources to grow.
结果：本组99例肾上腺肿瘤中，腺瘤32例，嗜铬细胞瘤41例，髓性脂肪瘤5例，皮质腺癌8例，转移瘤13例。
Results: Of 99 adrenal tumors, 32 cases were adenoma, 41 cases were pheochromocytoma, 5 cases were adrenal myelolipoma, 8 cases were adenocarcinoma and 13 cases were metastatic tumors.
椎管肿瘤常见的是星形细胞瘤(17.8%)、室管膜肿瘤和脂肪瘤(均为15.6%)。
The common entities of spinal tumors were astrocytomas (17. 8%), ependymal tumors and lipomas (15.6% each).
肾脏良性肿瘤包括：肾血管平滑肌脂肪瘤与肾瘤细胞瘤。这些非癌性肿瘤被认为是良性的，因为它们的生长仅限于肾脏内部。
Benign tumors include: angiomyolipoma and oncocytoma. These non-cancerous tumors are considered benign since they do not have the capacity to grow beyond the kidney to other sites in the body.
方法：采用体外培养S180肿瘤细胞为模型，观察肿瘤细胞的增殖、细胞膜上脂肪酸和唾液酸含量的变化，以及细胞膜流动性的改变。
Methods: S180 cell incubated in vitro was used as model. The change of proliferation of S180 cell, fatty acid and sialic acid in membrane and membrane fluidity of S180 cell were investigated.
