All types of cancer are believed to start due to an abnormal cell. When the genes that govern cell division are altered or damaged, they can lead to an abnormal growth of cells. If these abnormal cells survive, they may multiply further without any control, and lead to the formation of malignant tumors. The root cause of cancer can be pinned down to the presence of altered genes, referred to as mutated genes. Genes can be mutated at birth from heredity or occur spontaneously through an individual's lifetime due to multiple factors. While some factors, like lifestyle choices, can be changed to reduce the chances of occurrence of cancer, others like inherited gene mutations cannot be altered. More and more patients from Western countries are choosing to travel abroad for cancer treatments (oncology)
due to their affordability. China, India, Thailand, Singapore, Malaysia
and South Korea are some notable healthcare destinations
that provide medical tourists world-class quality cancer treatments at affordable costs.
