It is clear that genetic factors have a big relation and contribution to longevity and aging.  Genes much affect the longevity and increase the susceptibility effects to aging and diseases associated with recurring early death in families.  There are those inherited factors that contribute to aging. For instance, if a father has some aging characteristics, it is most likely that he will pass them to his children. In addition, if a family has the hereditary diseases, for instance diabetes, it is likely that it will be passed on to generations that family, same to just aging (Yang, 2012).

With age, cells and chromosomes also age. In fact, age is a result of the aging of chromosomes and cells. As chromosomes age, disintegrate and divide into two or more sub-cells, they grow weary and weak losing some energy (Yang, 2012).

Though aging may be inevitable to some extent, there can be some genetic treatment to slow down the aging process. Some of these may include first gene aging therapy, cosmetic treatments, maintaining the youthful morphology and adopting better nutrition (Yang, 2012).

At the presence of cancer, there results an abnormality and gradual uncontrolled cancer cells proliferation. Instead of a proper and appropriate response to the normal cell behavior signals hence cancer cells grow and divide in a much uncontrolled manner consequently invading normal tissues and organs (Yang, 2012).

Though cancer may be hard to control, it can be tamed by controlling some of its causes. For instance, cancer which results as a result of smoking can be controlled through avoiding the habit. Also, cancer can be controlled through nutrition and diet as advised by the nutritionists and avoiding stress after being diagnosed with the same. The lifestyle factors can be tamed and one reduces the risk of contracting cancer. However there are other causes like hereditary cause that maybe hard to control. Also caner as caused by age maybe a bit of a challenge to control (Yang, 2012).
