To Live Your Best Life, You Should Know The Ignored Causes of Cancer
What is the most Ignored cause of Cancer?
Cancer belongs to the
group of complex ailments that afflicts people across the globe. Presently, the
causes of cancer have been identified to be genetic factors, Lifestyle factors,
other infections, and environmental factors.
Lifestyle factors are drinking,
tobacco use, certain physical activities, and diet. Environmental factors are
described as radiation and exposure to chemicals. In the same vein, there are
infections which when present in the human body expose the sufferer to cancer.
The focus of many cancer
campaigns basically center on lifestyle, environmental and other infections.
But research points in the direction of genetic factors as the most recurrent
cause of cancer across the globe.
Genes Explained
Genes make up the DNA
and are therefore found in each cell within the human body. They control the
growth of each cell and tell them when to grow and split.
There are about
25,000 genes in each person and they are made up of particular DNA (deoxyribonucleic acid) sequence with the instructions for the production
of proteins, which in themselves have specific assignments in the human body.
Cells are able to use their genes in a selective fashion, as they turn
off the genes that are not required and activate the ones needed at every interval.
Gene Mutation
Mutations occur when
the DNA found in genes take on a life of their own or witness abnormal
behavior. It involves an alteration in the configuration of the basic genetic
make-up.
Genetic mutation can
either be inherited or acquired. Researchers have agreed that it requires more
than a single mutation for cancer to result. When it occurs in any cell, it is
passed on to every resultant offspring of that cell. Acquired mutations are more
common than genetic mutations and in most cases, they occur without the
knowledge of the sufferer.
Acquired mutations have
been proven to be responsible for most cases of cancer and mutation can also
occur in healthy genes that experience abnormal changes over a period of time.
It is also noteworthy that mutations occur regularly in human cells and when
the cell discovers this, it recovers and repairs the change. When repair fails, a signal is sent to the
cell to die and if it doesn’t and the mutation subsists, it might result in
cancer.
Failure of cell repairs
is also likely to occur when the cell responsible for sending the signal to
repair the mutation is affected by the abnormal changes. This will then aid the
growth of the mutant cell that spreads cancer through the cell streams.
Conclusion
Most people only get to
know there has been genetic mutation after they begin to experience the
symptoms of cancer. Early detection of mutant cells can make it easier to
control cancer and stop the spread.
