The root cause of many health problems, obesity, can lead to breast cancer as well. A new study has found that obesity results in stiffer breast tissue that promotes the growth of cancer.

Obesity leads to a stiffening of the mesh work material that surrounds fat cells in the breast, called the extracellular matrix, and these bio-mechanical changes create the right conditions for tumours, the findings showed.

ThinkstockPhotos-200302239-001-e1434141030608Women who are obese have a higher risk and a worse prognosis for breast cancer, but the reasons have remained unclear till now.

“We all know that obesity is bad; the metabolism changes and hormones change, so when looking for links to breast cancer, researchers almost exclusively have focused on the biochemical changes happening,” said study senior author Claudia Fischbach, associate professor of biomedical engineering at Cornell University in New York.

“But what these findings show is that there are also biophysical changes that are important,” Fischbach noted.
The findings could lead to recognition of stiffer breast cells as a clinical biomarker for breast cancer.

Also, the results should caution doctors against using certain fat cells from obese women in plastic and reconstructive breast surgeries, as these cells can promote recurring breast cancer.
The findings, published in the journal Science Translational Medicine, suggest clinicians may need to employ finer-scale imaging techniques in mammograms, especially for obese women, to detect a denser fat cells in the breast.

New Delhi, October 12, 2017:  In 2016, an Official data in had revealed that over 41 million children below the age of 5 were affected by obesity. Without due attention and efficient treatment, they are likely to remain obese throughout their lives, with an increased risk of developing a host of diseases and physical and psychological consequences like anxiety, low self-esteem, depression, diabetes, cardiovascular diseases and even premature death.

In view of an escalating number of people constantly coming under the ambush of obesity, and with childhood obesity becoming a cause of worry globally, the World Health Organization (WHO) released new guidelines on October 4, emphasizing the growing importance of healthcare experts and professionals, underlining their positive role in helping kids and teenagers fight the global menace.

What is Obesity?

Obesity is defined as ‘excess adipose tissue’. In other words, it is a body-weight disorder involving excessive body fat that exposes an individual to multiple health problems.  In case a person’s body-weight is nearly 20 per cent higher than it should be, he is considered obese.

There are different ways to calculate excess adipose tissue, the most common one being the Body Mass Index.

Index :

Overweight – BMI greater than or equal to 25

Obesity – BMI greater than or equal to 30

Global Data

According to data obtained by WHO, one half of all overweight children or obese children lived in Asia, and one-quarter of the total obese children lived in Africa.

According to a study published in The New England Journal of Medicine in June, India ranks second in the number of obese children in the world with China taking the first spot.

The global menace continues to rise rapidly in low and middle-income countries.

WHO Guidelines

The new report released by WHO on October 4 is titled ‘Assessing and Managing Children at Primary Healthcare Facilities to Prevent Overweight and Obesity in the Context of the Double Burden of Malnutrition’.

The report provides guidelines and updates for the Integrated Management of Childhood Illness (IMCI). The guidelines attempt to confine the spread of childhood obesity from expanding further, and prescribe undertaking proper assessment of dietary habits along with weight and height measurements. It also recommends dieting and proper counseling by healthcare experts.

Recommendations by WHO

  • WHO has recommended that primary healthcare facilities should be made available to all children below the age of 5 years and infants. These should include measurement of both weight and height of the children to determine their weight-for height and nutritional status as previously defined by WHO child growth standards.
  • For children and infants identified as overweight, healthcare experts should provide counseling to parents and caregivers on nutrition and physical activity, which includes creating awareness about healthy practices like exclusive breastfeeding in the first six months and continuing the practice until 2 years or more.
  • WHO also prescribes that an appropriate management plan should be devised to counter the menace in obese children. This can be developed by a trained health worker at primary healthcare facilities, or local hospitals.

Healthy Eating Tips to Fight Obesity

Here are a few healthy eating tips that will not only help you maintain a healthy weight but will also prove be be beneficial for your metabolism, physical strength and general well-being,

  • Refrain from unnecessary indulgences or random snacking and encourage healthy snacking choices like popcorns, yogurt, fruits, etc.
  • Reduce your sugar intake to less than 10 per cent of the total calories for an individual with normal weight.

New York, October 9, 2017 : Is your child not getting ample sleep due to early school hours? Beware, your kid is more likely to develop depression and anxiety, warns a new study. The study reveals that children, who start schooling before 8:30 a.m., get insufficient sleep or barely meet the minimum amount of sleep, that is 8-10 hours, needed for healthy functioning of the body.

“Even when a student is doing everything else right to get a good night’s sleep, early school start times put more pressure on the sleep process and increase mental health symptoms, while later school start times appear to be a strong protective factor for teenager,” said Jack Peltz, Professor at the University of Rochester in the US.

School timings not only affect the sleeping habits but also the daily functioning of the body. It aggravates major health problems like obesity, heart disease and others in adulthood. The study, published in the journal Sleep Health, suggested that maintaining a consistent bedtime, getting between eight and 10 hours of sleep, limiting caffeine, turning off the television, cell phone and video games before bed may boost sleep quality as well as mental health.

The researchers used an online tool to collect data from 197 students across the country between the ages of 14 and 17. The results showed that good sleep hygiene was directly associated with lower average daily depressive or anxiety symptoms across all students.

The risk of depression was even lower in the students who started school after 8:30 a.m. in comparison to those who started early. “One possible explanation for the difference may be that earlier starting students have more pressure on them to get high quality sleep,” Peltz stressed. (IANS)

All Breast Lumps are Not Cancerous, Says Radiologist Expert

New Delhi, Oct 7, 2017: Breast Cancer is one of the supreme causes of female deaths, however, it’s awareness is low in India. A leading Radiologist, Dr. Jyoti Arora, Associate Director, Medanta – the Medicity states that 8 out of 10 cases of breast lumps are not cancerous and undergoing biopsy is the only way to rule out breast cancer.

In India, two responses with respect to breast lumps are generally normal. Either the feeling of a lump formation in the breast is disregarded or the patient gets hysterical. The two responses are extreme and caused by the absence of proper awareness but in altogether different ways.

A recent study summarized that its predominance is as high as 25.8 per 1,00,000 women and its death rate are 12.7 per 1,00,000 women, mentioned ANI.

Dr. Arora has disclosed that because of the absence of awareness, a huge number of Indian women do not choose  appropriate tests and treatment.

Arora said, “One of the first symptoms of breast cancer is the formation of lumps in the breast. While many women from not so educated and aware sections of society do not identify lump in the breast as a reason enough to see the doctor, those who are aware of the connection between breast lumps and cancer does not realize that in 8 out of 10 cases, lumps in breasts are non-cancerous. For them, a breast lump is the synonym of breast cancer and they feel it’s the end of their life so do not get it evaluated.”

As the lumps are associated with pain, some females do not seek medical advice. The non-cancerous lumps are cyst formation, fibro-adenoma which is an abnormal non-cancerous growth, or maybe a temporary sign due to woman’s menstrual cycle.

Cancerous lumps are usually hard to feel and not associated with pain.

So if a female feels a lump, she should visit a breast specialist who will get a mammography and ultrasound done. If a solid lump is confirmed on imaging then in most of the cases biopsy would be needed to confirm whether the lump is cancerous or not.

To check cancerous cells, a radiologist removes tissue while conducting a breast biopsy from the suspected area for lab testing.

“There are various types of biopsies that a patient is offered. Tru cut needle biopsy is performed in majority of the cases, however when the abnormality is very small, subtle or when seen only on the mammograms in the form of calcifications or only on the breast MRI, vacuum-assisted breast biopsies (VABB) are preferred as they increase the accuracy and sensitivity of getting a representative sample from the abnormal area. Through VABB, more tissue can be removed than by the true cut needle biopsy and hence a more accurate report can be generated by the pathologist,” added Arora.

One should look for changes in the breast in terms of size and shape. Other than formation of lump, observe whether there are skin changes such as swelling and redness, in drawing of the nipples or if there is pain, irritation, change of color, or peeling and flaking of nipple skin.
