Cancer Prevention Tips

Either we like it or not, cancer affects most of us directly or indirectly. It’s Cancerhard to define, who is going to be the patient of cancer.

However cancer prevention is easier than we may think. With slight change in lifestyle, we can minimize our risk of developing any type of cancer.

Avoid smoking

All of us almost daily hear that, the smoking is injurious to health. Eve some packs of cigarettes deliver the warning “smoking causes lung cancer and heart diseases.” Smoking is the most important risk factor for cancers that is in our own control. Except lung cancer, smoking can be the main culprit for many other cancers.

Eyesight disorders and hear-shortfall may relate to each other

A new research has found a co-relation between hearing problems and diseases related to eye sight. The researchers discovered that eyesight_disorderssensorineural hearing disorder,the consequence of impairment of the nerves connect the ear to the brain or damage to the inner ear, has some link with eye sight problem.

It has been observed that almost half of the total cases have genetic reasons, in the background, to develop sensorineural hearing loss due to the GJB2 gene,generally taken as a responsible for it. A careful study tells that three children out of every 1,000 cases are the victims of sensorineural hearing damage.

To evaluate the study, linking together the eye problems with hear short fall, the researchers have assemblage the data on the children, suffering from sensorineural hearing loss.21.7 percent children have been found with eye disorders, divided in refractive and non refractive errors. Children having the percentage of 2.2 had the symptoms linked with eye problems and rest of 4.9 percent had those related to other than eye sight disorders.

Furthermore, when all the children were exposed to the test for genetic mutations in GJB2 gene, 18.8 percent had been found with two muted copies of the GJB2 gene, out of which, 3.7 percent had an eye problem. 11 out of 144 total children had no eye disorder. On the other hand, 20.8 percent had eye problems with no mutations.

The Role of Enzymes in Bone Metabolism

enzymes in bonePsycnodysostosis is a kind of a genetic disease characterised by short physique and that opens a window into how the joints could be destroyed by arthritis. Such a condition is caused by an enzyme called “Cathepsin K” that hampers the cells that break down the bones into bone modelling and repair; this further leads to bone resorption as well as brittle bones.

Cathepsin K has been studied largely using mouse pointers to study its role in bone metabolism. However, a new study observes its role in bone resorption in humans and concludes that it’s not required for bone break down.

The study took place in the Helsinki University Central Hospital in Finland and it involved a 55 year old patient suffering from Psycnodysostosis and also developed psoriatic arthritis(which is similar to psoriasis – a kind of a skin and nail disease).

Young Breast Cancer Survivors may Develop Disease in the Opposite Breast, a Dutch Study Finds

According to a Dutch study, young women who receive radiation after surgery for breast cancer are more likely to develop a new tumor in the opposite or contralateral breast and this risk is even higher in the women who have a significant family history of breast cancer.

The study will be published online in the Journal of Clinical Oncology current issue. In this study, the researchers examined some fairly recent radiation techniques and some experts have pointed out these techniques have been improved and refined with the passage of time.

Dr. Jay Brooks, who is chairman of hematology/oncology at Ochsner Health System in Baton Rouge, La, says about this study: “Though it’s quite interesting, over the last 25 years radiation techniques have dramatically changed and many patients were treated with much older techniques.”
