Part A : Defects in DNA Replication Cause Cancer
As known today, cancer is one of the most lethal diseases in the world. Millions of people died every year caused by various type of cancer, but the concern is that what does really caused the cancer itself? Is it because of the lifestyle people have nowadays? Or because of environment that has changed? Or even sometimes because of the flaw in the replication of DNA? There are lots of probabilities to cause cancer.
In this section, we will discuss about how does DNA replication could end to cause cancer.
II. Replication of DNA
DNA replication is a process to create two identical molecules of DNA by unification of the DNA on the parent DNA (DNA template). New DNA strands…show more content…
Well, there is a lot of factor leading to cancer. But there are some major factor that have take a big part in causing cancer to human. Major causes why cancer happened in human is because of consumption of tobacco and was found in 1964 as the biggest factor that lead to lung cancer by US surgeon (Anand et al., 2008). Other big factor that proved caused of cancer is a lot of alcohol drinking.
Alcohol consumption is an established risk factor for cancers of the mouth, pharynx, larynx, esophagus, liver, colorectum, and female breast, and there is some evidence of an association with pancreatic cancer (The American Cancer Society, 2011).
Radiation risked human to cancer. That comes with the fact that one of the most common cancer is caused by radiation, it could be because of some common radiation in example UV (ultraviolet) light, X-ray, etc.
Exposure to UV radiation is a major risk for various types of skin cancers including basal cell carcinoma, squamous cell carcinoma, and melanoma (Anand et al., 2008).
Diet also lead people to cancer, consumption of red meat in big amount with specific amount of time could lead to intestine cancer. Nitrates and nitrites in meat interfere botulinic exotoxin production in the body (Divisi, Tommaso, Salvemini, Garramone, Crisci, 2006).
People who are obese have a higher risk of cancer than the normal people are.
People with cancer must be treated with particular treatment as it’s a state where they
