DOGS : Your dog can save your life! Cancer-sniffing dogs

study showed that trained explosive-detection sniffer dogs can detect prostate 

cancer in urine in 93% of cases

-Cancer-sniffing dogs are saving lives-

researchers trained two sniffer dogs to identify urine samples from men with 

prostate cancer. They then allowed the dogs to sniff urine samples from men 

with or without prostate cancer and indicate which ones had the prostate 

cancer smell.

One dog correctly identified all the samples from men with prostate cancer, 

and the other dog identified 98.6% of them.

This study suggests dogs can be trained to differentiate between urine samples 

from men known to have prostate cancer and people without the condition. But 

further testing should be carried out to test whether the dogs can accurately 

detect men with prostate cancer who are not yet known to have the disease

although The researchers concluded that a trained sniffer dog can identify

chemicals specific to prostate cancer in urine with a high level of 

accuracy,it seems unlikely that dogs would be routinely used on a widespread basis to

detect prostate cancer instead of the traditional testing methods such as(PSA) test.

PSA - prostate specific antigen-is a protein produced by the prostate.

The PSA test is a blood test that measures the amount of prostate specific 

antigen in the blood. 

This type of study is suitable for an early-stage assessment of the promise of 

a new test. If successful, researchers would need to go on to test samples of 

men who are currently undergoing assessment for suspected prostate cancer, 

rather than those already known to have the disease. This would better assess 

how the dogs would perform in a real-world clinical situation.

-Now your best friend can save your life-

although There's no proper research to show that untrained dogs can detect 

cancer,some dog owners reported that they were lucky because their beloved 

dogs alerted them to cancer by nuzzling  Certain body part insistently.

-Dogs can smell cancer on your breath-

other studies have also found that dogs are able to sniff lung cancer on 

humans' breath 

And there are probably other medical conditions that dogs may be able to train 

to assist with and help people stay healthy.

Obesity and Overweight Health Consequences | Weight loss Health Benefits

The health consequences of obesity and overweight are many and varied, ranging from an increased risk of premature death to several non-fatal but debilitating and psychological complaints that can have an adverse effect on quality of life. 

The degree of risk is influenced for example, by the relative amount of excess body weight, the location of the body fat, the extent of weight gain during adulthood and amount of physical activity. Most of these problems can be improved with relatively modest weight loss (10 to 15%), especially if physical activity is increased too.

The major health problems associated with obesity and overweight are:

Type 2 diabetes
Cardiovascular diseases and hypertension
Respiratory diseases (sleep apnea syndrome)
Some cancers
Osteoarthritis
Psychological problems
Alteration of the quality of life

 Type 2 diabetes

Of all serious diseases, it is Type 2 diabetes (the type of diabetes which normally develops in adulthood and is associated with overweight) or non-insulin-dependent diabetes mellitus (NIDDM), which has the strongest association with obesity and overweight. Indeed, the risk of developing Type 2 diabetes rises with a BMI that is well below the cut-off point for obesity (BMI of 30). Women who are obese are more than 12 times more likely to develop Type 2 diabetes than women of healthy weight. The risk of Type 2 diabetes increases with BMI, especially in those with a family history of diabetes, and decreases with weight loss 

Cardiovascular disease and hypertension

Cardiovascular disease (CVD) includes coronary heart disease (CHD), stroke and peripheral vascular disease. These diseases account for a large proportion (up to one third) of deaths in men and women in most industrialised countries and their incidence is increasing in developing countries. 

Obesity predisposes an individual to a number of cardiovascular risk factors, including hypertension and elevated blood cholesterol. In women, obesity is the third most powerful predictor of CVD after age and blood pressure [20]. The risk of heart attack for an obese woman is about three times that of a lean woman of the same age.

The association between hypertension (high blood pressure) and obesity is well documented and the proportion of hypertension attributable to obesity has been estimated to be 30-65% in Western populations. In fact, blood pressure increases with BMI; for every 10 kg increase in weight, blood pressure rises by 2-3mm Hg. Conversely, weight loss induces a fall in blood pressure and typically, for each 1% reduction in body weight, blood pressure falls by 1-2mm Hg.

The prevalence of hypertension in overweight individuals is nearly three times higher than in non-overweight adults and the risk in overweight individuals aged 20-44 years of hypertension is nearly six times greater than in non-overweight adults.

Cancer

Although the link between obesity and cancer is less well defined, several studies have found an association between overweight and the incidence of certain cancers, particularly of hormone-dependent and gastrointestinal cancers. Greater risks of breast, endometrial, ovarian and cervical cancers have been documented for obese women, and there is some evidence of increased risk of prostate and rectal cancer in men. The clearest association is with cancer of the colon, for which obesity increases the risk by nearly three times in both men and women.

Osteoarthritis

Degenerative diseases of the weight-bearing joints, such as the knee, are very common complications of obesity and overweight. Mechanical damage to joints resulting from excess weight is generally thought to be the cause. Pain in the lower back is also more common in obese people and may be one of the major contributors to obesity-related absenteeism from work.

Psychological aspects

Obesity is highly stigmatised in many European countries in terms of both perceived undesirable bodily appearance and of the character defects that it is supposed to indicate. Even children as young as six perceive obese children as “lazy, dirty, stupid, ugly, liars and cheats” . 

Obese people have to contend with discrimination. A study of overweight young women in the USA showed that they earn significantly less than healthy women who are not overweight or than women with other chronic health problems .

Compulsive overeating also occurs with increased frequency among obese people and many people with this eating disorder have a long history of bingeing and weight fluctuations .
