Indicаte whether eаch оf the fоllоwing stаtements related to cancer is likely to be true or false. Cancer cells contain mutations in the genome, but their chromosome number and structure are always normal. [1] Even though cancer cells divide faster than normal cells, they are less dependent on other cells to provide growth factors. [2] Because certain mutations in proto-oncogenes contribute to cancer development, cancer researchers should be attempting to design drugs that will decrease the activities of proto-oncogenes. [3] The inhibition of negative immune regulation has been used to develop anti-immune-checkpoint antibodies. These antibodies release a killer cell attack on cancer cells. This has been used for effective treatment of metastatic melanoma. [4] P53 should be classified as a potential oncogene. [5] Tumor progression involves successive rounds of randomly inherited changes followed by natural selection. [6]
