Are tumor cells and cancer cells the same thing?

Tumor cells and cancer cells are not necessarily the same. The details are as follows:

Tumor cells are divided into benign tumor cells and malignant tumor cells. Malignant tumor cells originating from mesenchymal tissue are called sarcomas, while those arising from epithelial tissue are called carcinomas. Therefore, cancer cells represent only a subset of tumor cells. Benign tumors grow slowly and are typically cured through surgical removal. Malignant tumors are relatively rare among tumor cells but carry a poor prognosis. They progress rapidly and have become a serious threat to human health. Thus, the cells of benign tumors are not cancer cells, and even malignant tumor cells derived from mesenchymal tissue are not classified as cancer cells. Only malignant tumor cells originating from epithelial tissue can be referred to as cancer cells, such as lung cancer cells, breast cancer cells, etc.

If patients experience any discomfort, they should seek timely medical treatment at a hospital. Regular, moderate physical exercise may help enhance their immune system. Attention should also be paid to dietary adjustments, avoiding spicy and greasy foods.
