Mutations that accumulates overtime in chromosomes of these cells are found in malignant tumours. When such errors occurs placing a gene in close proximity to different control region, these errors may affect the different control region and cause them to lose their functions. Most of them function to regulate the rate at which the cell divides but when these errors occur, they lose their function and the cells divides uncontrollably making the cancer worse and even to metastasis.
Cancer cells normally cause a gene product to be excessively expressed or just expressed at concentrations that are higher than the normal. Meaning it will over produce a product that is not needed in the body which in turn leads to the deteriorating health.
Explanation: In group therapies, several people who share a common problem all meet regularly with a therapist to help themselves and one another; the therapist acts as a facilitator.
