Cancer is caused by genetic changes leading to uncontrolled cell growth and tumor formation. The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. [1] [2] A minority of cancers are due to inherited genetic mutations. [3] Most cancers are related to environmental, lifestyle, or behavioral exposures. [4]
7 gru 2022 · Cancer is caused by changes (mutations) to the DNA within cells. The DNA inside a cell is packaged into a large number of individual genes, each of which contains a set of instructions telling the cell what functions to perform, as well as how to grow and divide.
11 paź 2021 · Explanations about what cancer is, how cancer cells differ from normal cells, and genetic changes that cause cancer to grow and spread.
3 lut 2022 · Cancer is a leading cause of death worldwide, accounting for nearly 10 million deaths in 2020, or nearly one in six deaths. The most common cancers are breast, lung, colon and rectum and prostate cancers.
17 sty 2023 · Cancer occurs when genetic mutations in abnormal cells cause them to divide rapidly and can spread to other tissue and organs. Learn about the main causes of cancer, the risk factors that increase your chance of developing it, the types of cancer, and how to detect and treat it.
Cancer starts with changes in one cell or a small group of cells in the body. These changes are called mutations and they affect the genes that control how cells grow and divide. Learn more about cell changes, gene mutations and how they cause cancer.
Learn how genetic changes in cells cause cancer to grow and spread, and how cancer statistics help scientists understand the burden and progress of this disease. Also, explore how cancer disparities affect certain groups of people and what factors contribute to them.
