Healthy lifestyle crucial for cancer prevention

New York: Offering a new explanation for what drives cancer, recent research has shown that cells with cancerous mutations can suddenly find themselves most fit, allowing their population to expand when the tissue ecosystem changes due to ageing, smoking, or other stressors. mother-491952_640

Arguing against the commonly held “accumulation of mutations” model of cancer, the study favors a model that depends on evolutionary pressures acting on populations of cells. It, therefore, contends that the ecosystem of a healthy tissue landscape lets healthy cells out compete ones with cancerous mutations.

This new thinking about what drives cancer development may have profound implications for cancer therapy and drug design.

“We have been trying to make drugs that target mutations in cancer cells,” said study senior author James DeGregori, associate director for basic science at University of Colorado Cancer Center in the US.

“But if it is the ecosystem of the body, and not only cancer-causing mutations, that allows the growth of cancer, we should also be prioritizing interventions and lifestyle choices that promote the fitness of healthy cells in order to suppress the emergence of cancer,” said DeGregori.

The proposed model, presented in the journal PNAS, helps to answer a longstanding question in cancer science known as Peto’s Paradox — if cancer is due to random activating mutation, larger animals with more cells should be at greater risk of developing the disease earlier in their lives.

Well, then why do mammals of vastly different sizes and lifespans all seem to develop cancer mostly late in life? The answer to this proposed by researchers is that in addition to activating mutation, cancer may require age-associated changes to the tissue landscape in order for evolution to favor the survival and growth of cancer cells over the competition from healthy cells.

  • Do you want to stay fit and longer? Daily push-ups and sit-ups may add a few extra years to your lifespan, reveals new research.

Benefits of doing Strength-based Exercise

The research found that the people who did strength-based exercise had a 23 percent reduction in risk of premature death and a 31 percent reduction in cancer-related death.

“The study shows that strength-based exercise may be just as important for health as aerobic activities like jogging or cycling,” said Emmanuel Stamatakis, Associate Professor at the University of Sydney in Australia.

“And assuming our findings reflect cause and effect relationships, it may be even more vital when it comes to reducing the risk of death from cancer,” Stamatakis added.

The researchers observed 80,306 adults for two years and made some adjustments in order to reduce the influence of certain factors such as age, sex, health status, lifestyle behavior and educational level.

All participants with established cardiovascular disease or cancer at the baseline and those who passed away in the meanwhile were excluded from the study.

The research, published in the American Journal of Epidemiology, showed that exercises performed using one’s own body weight without specific equipment were just as effective as gym-based training.

“When people think of strength-based exercise, they instantly think of doing weights in a gym, but that doesn’t have to be the case,” noted Stamatakis.

“Many people are intimidated by gyms, the costs or the culture they promote, so it’s great to know that anyone can do classic exercises like triceps dips, sit-ups, push-ups or lunges in their own home or local park and potentially reap the same health benefits,” the researcher said. (IANS)

Yami Gautam tries out different ways to stay fit

The actress Yami Gautam, who got associated with Quaker Oats to talk about the importance of consuming a healthy breakfast through a live Facebook session, is willing to change her physical appearance as long as a project is convincing enough.

“It totally depends. It’s not easy, but I cannot give a subjective answer to this question. But I feel if there is a role that I love and love the team, then I would take it as it comes,” said the model turned actress.

Apart from her work, the “Sanam Re” actress is also known for being fit. She says she makes a “conscious effort to stay fit and feel good”.

“The kind of profession I am in, and the active lifestyle we all lead requires us to be on our toes all the time. Which is why it becomes all the more important to maintain a healthy and balanced lifestyle. Keeping fit is not about a good core or a good body, it is a lifestyle choice which reflects every day. It even translates to little things like good skin and hair, amongst others,” Yami said.

What is her fitness regime?

“I do mostly functional training. I do very little weights. As I said, it always is an amalgamation of pure workout and your diet. It doesn’t mean cutting down food. It means including more healthy stuff in your food, that gives you the right nutrition intake.”

Yami feels each individual finds their own way to a healthy lifestyle.

“It’s not always restricted to the gym. I dance, someone does yoga, someone goes cycling. I think any sort of physical activity and right food is very important. I think even right food doesn’t mean it has to be bland and boring.

“Healthy food can be yum too. For instance, as part of Breakfasts of India, I cooked Dakshini Toast with Quaker Oats – a recipe that was healthy, tasty and easy to make. I truly believe you must enjoy what you are eating.

“Keep one day to indulge, I never call it a ‘cheat day’ because I feel you deserve it,” the Yami Gautam said.(IANS)

Butterfly IQ : The iPhone-based Portable Ultrasound Machine to Detect Cancer

Developed by Connecticut-based start-up Butterfly Network, the pocket sized device works by shooting sound into the body and capturing the echoes.

New York, October 29, 2017 : A novel iPhone-based portable ultrasound machine that can help detect cancer easily at home has been developed by US researchers.

The device called Butterfly IQ is a scanner of the size of an electric razor that can display black-and-white imagery of the body, when paired with an iPhone.
Developed by Connecticut-based start-up Butterfly Network, the pocket sized device works by shooting sound into the body and capturing the echoes.
Usually, the sound waves are generated by a vibrating crystal. But Butterfly’s machine instead uses 9,000 tiny drums etched onto a semiconductor chip, reported the MIT Technology Review on Friday.
Earlier this year, John Martin, a US-based vascular surgeon and chief medical officer at Butterfly Network, discovered a cancerous mass in his own throat while testing the device.
Martin felt an uncomfortable feeling of thickness on his throat, thus he oozed out some gel and ran the probe along his neck.
On his smartphone, to which the device is connected, black-and gray images quickly appeared.
He found a 3 cm mass that was diagnosed as squamous-cell cancer — a form of skin cancer that develops in the cells of the outer layer of the skin.
Instead of vibrating crystals, Butterfly IQ uses “capacitive micro-machined ultrasound transducers”, or CMUTs, tiny ultrasonic emitters layered on a semiconductor chip a little larger than a postage stamp.
“The device gives you the ability to do everything at the bedside: you can pull it out of your pocket and scan the whole body,” Martin said.
The company now plans to combine the instrument with artificial-intelligence software that could help a novice position the probe, collect the right images, and interpret them.
By 2018, its software will let users automatically calculate how much blood a heart is pumping, or detect problems like aortic aneurisms, the report said.
The Butterfly IQ is the first solid-state ultrasound machine to reach the market in the US. The company plans to go on sale this year for $1,999-far less than any other model on the market. (IANS)
