Colorectal cancer on rise among young adults

With the rise in incidence of colorectal cancer (CRC) among adults, it could no longer be considered a disease of older people, according to a study.

Although men in older age groups are well recognised to have higher incidence of colon and rectal cancer, there is little difference in the incidence rates between men and women aged below 40 years.

For the study, published in the BJS (British Journal of Surgery), the researchers from the University of Bristol, UK, examined data on adults, diagnosed with colorectal cancer in England between 1974 and 2015.

The CRC, also known as bowel cancer, colon cancer, or rectal cancer, is the development of cancer from the colon or rectum (parts of the large intestine).

According to the study, of the 1,145,639 CRC cases among adults aged over 20 years between 1974 and 2015, 2,594 cases were in the 20-29 year age group, 11,406 in the 30-39 year age group and 42,134 in the 40-49 year age group.

The most sustained increase was seen in adults aged 20-29 years, the study said. The magnitude of increases was similar in both sexes and across income levels, it added.

The most pronounced increases was in the southern regions of England, according to the researchers and added, young patients needed more treatment to achieve similar outcomes than older people.

Changes in incidence rates could be used to plan future screening policy, preventative strategies, research agendas as well as increasing public understanding that younger people must be aware of symptoms of colorectal cancer, the researchers said.

The University of Bristol, the research university in Bristol, England, is ranked 49th by the QS World University Rankings 2020. It's ranked in the top 10 of UK universities in 2020.

Reboiling Water Can Be Detrimental to Your Health

The composition of water changes when boiled. This beneficially releases volatile compounds and gases, making boiled water a safe drink. But when ordinary water is over boiled or reboiled, the chemical compounds change for the worse. Instead of dissolving, dangerous substances accumulate, increasing the risk of consuming certain chemicals and harmful substances like nitrates, arsenic and fluoride (see more in the section below). Healthy minerals may also turn for the worse when 'amassed': in large quantities, calcium salts, for instance, can lead to kidney stones and gallstones. 

 

The damaging effects of reboiled water

Nitrates that are exposed to high heat become highly toxic. High temperatures transform nitrates to nitrosamines, which are carcinogenic (having the potential to cause cancer). Nitrates have also been linked to diseases like leukemia, non-Hodgkin lymphoma, ovarian, colon, rectal, bladder, stomach, pancreatic and thyroid cancer. 

In addition, over the years, an accumulation of arsenic (a chemical element that occurs in many minerals) can lead to arsenic intoxication, which has been shown to cause numerous health issues including cancer, cardiovascular disease, neurological issues, infertility and developmental disorders. 

Furthermore, being exposed to too much fluoride can have damaging effects on neurological and cognitive development, particularly in children, according to research.

So, take precautions today! If you must reboil your water, be sure to change it first. Happily, however, reboiling is fine if you are using perfectly pure distilled deionized water, where no ill-effects have yet been noted. 

Consumption of Beef linked to Colon cancer

Consumption of beef raised the risk of colon cancer, according the evidence from around the world, according to a Noble Laureate. According to him, the low incidence of colon rectal cancer in India cold be due to less consumption of beef here., (except in Kerala).

South American countries like Argentina, Uruguay, the US, Australia & Europe, where red meat is favoured, witness a high incidence of this form of cancer, according to researchers. They said high rectal cancer may be caused by undiscovered heat-resistant carcinogens present in beef & its products. These may be undiscovered carcinogens, which are thermo-resistant, present predominantly in beef. Some polymaviruses are known to survive temperatures up to 80 deg C for 30 minutes leading to their survival in partially cooked meat, they said.

Red meat could also be linked to breast cancer & lung cancer in the West, according to the Nobel laureate.

But in India, the reasons for the high incidence of breast cancer, despite low consumption of red meat could be linked to dairy products, he said.

With cervical cancer being a common cancer among Indian women, he felt that administering vaccines against the pappillomavirus to men & not just women  alone could help restrict its spread & help in its eradication.

Legumes, brown rice, veggies, greatly reduce risk of colorectal cancer

Eating legumes at least three times a week and brown rice at least once a week can reduce your risk of colon polyps by 33 percent and 40 percent respectively, thereby decreasing your risk for colorectal cancer to a great extent, according to a new research.

Results also show that consuming cooked green vegetables once a day or more, as compared to less than five times a week, was associated with a 24 percent reduction in the risk of rectal/colon polyps.

Meanwhile, consuming dried fruit three times a week or more, versus less than once a week, was associated with a 26 percent reduced risk.

Eating these foods is likely to decrease your risk for colon polyps, which would in turn decrease your risk for colorectal cancer according to a  doctor.

The protective effects of these foods could be due in part to their cancer-fighting agents, the study reported.

Legumes, dried fruits, and brown rice all have a high content of fiber, known to dilute potential carcinogens.

Additionally, cruciferous vegetables, such as broccoli, contain detoxifying compounds, which would improve their protective function.
