New breakthrough in skin cancer research

February 28, 2011

An international team of scientists, has discovered the reason why a rare skin cancer called multiple self-healing squamous epithelioma (MSSE), heals by itself.

The scientists said understanding how tumours that lack the gene known as TGFBR1 behave will help them predict the clinical effects of drugs that target these cancer-promoting or cancer-inhibiting signals. Read more…

New test more accurate to diagnose breast cancer

February 26, 2011

Detecting breast cancer in its earliest stages is very important to treating it and long-term survival. So what if you could diagnose breast cancer even before a mammogram picks up a small lump.
Well, in a preliminary study of a few dozen women, doctors were able to diagnose breast cancer with a simple breath test. People with cancer have small amounts of telltale chemicals in the breath and now new technology can pick up those chemicals. Read more…

New laser-based tool ‘detects signs of skin cancer’

February 25, 2011

High-resolution images from a laser-based tool could help doctors better diagnose melanoma, the deadliest form of skin cancer.
The tool probes skin cells using two lasers to pump small amounts of energy, less than that of a laser pointer, into a suspicious mole.For the first time, scientists have the ability to identify substantial chemical differences between cancerous and healthy skin tissues.
Using the amount of eumelanin as a diagnostic criterion, the team used the tool to correctly identify all eleven melanoma samples in the study. Read more…

Pot Helps Cancer Patients Eat, Sleep

February 24, 2011

A recent study finds that the primary active ingredient in marijuana – tetracannabinol, or THC – may help cancer patients improve their appetites and sleep habits.
While the overall caloric intake between subjects in the control and experimental groups did not significantly vary, many who were given the THC pill reported that they found the food that they did eat tasted better. They also reported improved patterns of sleep and relaxation.
These findings are not considered to be revolutionary, but they may serve to further the cause of individuals and organizations which advocate the use of medicinal marijuana. Read more…

Breakthrough in breast cancer research

February 23, 2011

The enzyme lysyl oxidase-like 2 (LOXL2) is needed for tumour cells to escape from the breast and invade surrounding tissue, thereby allowing cancer cells to travel to distant organs. Using laboratory models, the team showed that blocking the function of LOXL2 significantly decreased the spread of the cancer from the breast to the lungs, liver and bone.
Study suggests that drugs which block this enzyme may be effective in preventing patients’ cancer from spreading,” lead researcher Dr Janine Erler said. In Britain alone, around 12,000 women die from breast cancer each year, mostly because their cancer has spread to other parts of their body. In 2008, 47,693 women were diagnosed with breast cancer.

Cancer: ‘Prevention better than cure’

February 22, 2011

Cancer is an unusual or abnormal uncoordinated growth of tissue beyond the normal tissue in any particular area of the body. There are organs of the body that are highly susceptible to it. It affects virtually every part of the body. It is important to note that those ones that are very common are cancer that could be prevented, but if it is not prevented one can improve the survival rate through early detection. Much of these can come around through awareness. You need to know what it is all about before you talk of people going for the screening to detect it and get the precautions that you need, to ensure that you are not down from cancer, because it has become a major problem in our society.
Cancer is a disease that affects virtually everybody, male and female; black or white; young or old. Specific cancer affects different age groups and sexes. It is not a new disease but a disease that has been neglected overtime because much attention was not paid to it.
This is borne out of the fact that, it is a slow developing disease. Because it does not usually come down with immediate issues that one would report to the hospital or screening centres, so people tend to neglect it. Most times cancers are yet to be known even to the person having it. It is when they are late that is when they begin to manifest symptoms. But at the early stages they do not manifest anything. So people do not have any cause to go to the hospital. It is on the rise and also becoming a very major killer of men, women and children. Read more…

Premature baldness linked to prostate cancer

February 21, 2011

Group of 699 patients who were all either middle-aged or older. Out of that group, 388 of them were said to be suffering from prostate cancer during the study. The idea was to see if there was any correlation between early baldness and prostate cancer later in life. What researchers found is that people who developed baldness early, in their 20s, were far more likely to suffer from prostate cancer later in life. The belief is that this is due to high testosterone levels in these people, as well as genetic traits that are linked between the two diseases. Overall, the risk of prostate cancer later in life for these men who developed premature baldness was said to be doubled. Prostate cancer is extremely common, and kill a quarter-million people each and every year. Read more…

First breast cancer gene

February 19, 2011

A GENE which causes ­aggressive breast cancer has been found by scientists.
Named ZNF703, it is responsible for about 4,000 cases a year, or one in 12 of the total. It causes the disease by speeding up a cell’s growth rate, making it and daughter cells divide permanently.
Experts said the discovery, which is the first of its kind in five years, could lead to better treatments. Read more…

Cervical cancer curable

February 18, 2011

There is no denying the fact that cases of cervical cases have been rising. As per records, out of the 6,000 new cancer patients detected in the city each year, around 1,000 are women who suffer from this disease. However, cervical cancer is curable if detected in early stages.
One of the major risk factors that leads to such changes is the human pappilloma virus (HPV). HPV is a group of viruses that can infect the cervix. It is one of the causes of nearly all cervical cancers. The virus is transmitted through sexual contact and if it persists for a longer duration in the genital tract then it becomes infectious. Mostly, women from rural background, least aware about the importance of hygiene of the genital organs, are prone to the disease.
Smoking slightly increases the risk of cervical cancer. Infection with HIV, or taking drugs that suppress the immune system also increase the risk.
Cervical cancer is more common among women who do not go for regular Pap tests. The Pap test helps doctor to find abnormal cells. If the cellular changes are diagnosed early then killing the cells before turning cancerous can prevent cervical cancer. Doctors say women can reduce the risk of cervical cancer by regular Pap test.

Popular Bone Drugs Linked to Reduced Colon Cancer Risk

February 17, 2011

People who take drugs called bisphosphonates to prevent bone loss may also reduce their risk of developing colorectal cancer by almost 60 percent compared to those not on the drugs.
The researchers found that taking bisphosphonates, mostly Fosamax, for at least a year was associated with a significant 59 percent reduction in relative risk for colorectal cancer.
The lowered risk of colorectal cancer seen with bisphosphonates may be due to the way the drug acts in the body, which is similar to how cholesterol-lowering drugs called statins work. Read more…
