What is the difference between cysts and tumors?


@healthbiztips by Arlene Gentallan

A lump under the skin is often a cause of concern. Could it be a cyst or a tumor?

The difference between a cyst and a tumor can often be tricky. Both cysts and tumors can grow in any part of the body, from the superficial layer of the skin to deep inside internal organs and bones. Both can also vary in size from microscopic to large abnormal growth that can displace normal tissue.


What is a Cyst?


Cysts is an encapsulated sac filled with either air, fluid, pus, or cell debris. Most cysts are benign.

Take note that cysts are encased in a membranous tissue.


What is a tumor?


On the other hand, a tumor is an abnormal growth of cells that forms a mass which can either be benign (localized to a certain area of the body) or malignant (cancerous cells that can spread to other parts of the body). 

Under normal condition, worn off cell die and are replaced by new cells, however, in the case of tumor, old cells that no longer effectively function do not die, but instead they keep on multiplying, forming a mass called a tumor.

Malignant tumor have the ability to form cysts.


How to know if a cyst or a tumor is cancerous?


A common concern that arise from having a cyst or tumor is the question whether or not the particular growth is benign or malignant. The only confirmatory test to determine if a growth is malignant is through biopsy, a test in which tissue sample from the growth is taken to be analysis under a microscope.

Breast Cancer risk Increased by Light Exposure at Night

Breast Cancer risk Increased by Light Exposure at Night

Many of us can be guilty of using our mobile phone or computer at bedtime, yet this action increases our risk of getting breast cancer.

This research finding raises concern considering breast cancer is the most frequent form of cancer that affects and kills women.

Normally, when it is bedtime, our brain releases a hormone called "melatonin" that has an anti-cancer effect. Normally, we produce more of this hormone while we are sleeping.

When we are expose to light at night, it messes up with the melatonin secretion causing it's level to decrease.

Phones and computers are not the only culprit of exposure to light at night, even artificial lights such as LED light and television are offenders.

A sound sleep really helps cut down breast cancer risk, however it remains a challenge.

Working the night-shift is also a contributing factor for the development of invasive breast cancer because it messes up the body's internal biological clock.

Don't underestimate the role of sleep in our well-being. As we age, a sound good night's sleep really does play a crucial role in keeping us healthy and energized.


If you or a person you know is at increase risk of developing cancer (possibly due to family history), please share this health fact.

How Sunlight Impacts our Psychology - Healthbiztips

How Sunlight Impacts our Psychology

You may have known that exposure to sunlight is a beneficial to the body in that it stimulates the skin to produce Vitamin D, but did you know that sunshine has a tremendous impact on our mind.

Research has shown that immersion to direct sunlight uplifts the mood, reduces anxiety, increases feeling of satisfaction, and lessens stress.

On the other hand, lack of enough exposure to sunlight, especially due to weather condition or the season, is strongly linked to mental health problems such as Seasonal Affective Disorder (a type of depressive disorder that affects a person during the fall and winter season).

Depressed people are particularly vulnerable to sunshine's positive psychological effect. So, if a person is already suffering from depression but prefers to stay indoor with minimal exposure to sunlight, it can potentially lead to memory impairment and cognitive decline.
Sunlight improves blood flow to the brain. Furthermore, it regulates the wake-sleep cycle (circadian rhythm). Sunshine also balances crucial chemicals in our brain such as serotonin and melatonin.
Exposure to sunlight triggers our brain to release more serotonin, but less melatonin. The increase in the neurotransmitter serotonin uplifts the mood and reduces depressive symptoms. Meanwhile, the decrease in the sleep hormone melatonin causes the person to become energetic and attentive.


It goes without saying that sunshine plays a crucial role in keeping us healthy both mentally and physically. Waking up to a nice warm sunshine is refreshing and invigorating.

Sleep Deprivation accelerates Atherosclerosis - Healthbiztips

Lack of Enough Sleep puts you at risk of Heart Disease

Don't underestimate the risks you're taking when you're not getting enough sleep. Here's why...

Disrupted sleep raises inflammation in your body.

A study published in "Nature" reveals that lack of enough sleep raises inflammatory white blood cells such as neutrophils and monocytes which subsequently accelerates atherosclerosis.

Atherosclerosis (also known as arteriosclerosis) is the build up of plaque in the inner walls of arteries, which eventually hardens and narrows the blood vessel. In the long run, atherosclerosis can lead to fatal cardiovascular events such as heart attack and stroke.

The Role of Hypocretin

Research in mice unravel a pathway by which a brain-secreted hormone called "hypocretin" subdues the formation of inflammatory white blood cells.

Mice that are subjected to sleep deprivation were observed to have significantly lower levels of hypocretin. This in turn, causes an increase production of inflammatory white blood cells "monocyte", which subsequently causes the subject to develop larger arterial plaque.

In contrast, experimental mice that had enough and uninterrupted sleep had higher level of hypocretin causing lesser inflammatory cell production and reduced risk of arterial plaque build-up.

Amazingly, sleep deprived mice that received hypocretin supplement had lower levels of inflammatory cells and smaller formation of arterial plaque.
What is hypocretin? It is a hormone produced by the hypothalamus of the brain that has been found out to play an essential role in the regulation inflammatory white blood cell production. It mediates an anti-inflammatory pathway.

A sound sleep protects your heart.

Undeniably, especially to the working class, one of the best feelings in life is waking up from a good night's sleep. Now, besides your insurance, a good night sleep is arguably one of the best free investment you can take to save yourself from the demise of a fatal cardiovascular disease. Think about it.


Note:

The study was not on mice. Further research is still needed to fully appreciate and explore it's impact to human health.

Japanese Healthcare Review - Healthbiztips

Japanese Healthcare Review

In 2018, the World Health Organization listed Japan as having the longest life expectancy among all other countries, with an average lifespan of 84.2 years.

So, what can we expect from the health care system of a nation whose people live amongst the longest lifespan on Earth? Aren't you curious?

Let's talk about Japanese health care system.

@healthbiztips by Arlene Gentallan

Japanese health care is universal because it gives everyone in Japan the opportunity to quality health care under the National Health Insurance system.

Japanese National Health Insurance system covers as much as 70% to 90% of medical bills.
Japan has a universal health care system -- It covers everyone in Japan
 Japan has a National Health Insurance System that ensures health care is provided to Japanese Citizens. Even, foreigners staying in Japan for more than a year can apply for a health insurance.

People still have to pay their health insurance but factors like income, type of work, age, and residence strongly determines how much people pay. Which is good since people won't have to pay more than what they can afford.

Also, for employees, half of their health care insurance fee is shouldered by their respective companies.

Japan's National Health Insurance system provides free annual physical examination to it's people.

Japan's successful healthcare system is a feat they have to credit their government for. The Japanese government takes active part in regulating their health care system through rules and policies such as a mandating a fix health care fee across the country, and requiring hospital to run as non-profit institutions.


Japan's Health Care System is Advance

Japan is a technologically advance nation so it wouldn't come as a surprise that their hospital equipments and tools live up a high standard.

You'll be assured of the best quality of health care standard in Japan.


Cheaper

One of the biggest advantage of living in Japan is it's incredibly cheap medical cost. Healthcare here is run as a non-profit which really do serve it's people well.


Emergency care

Most Japanese hospital's emergency room are not open 24/7. Emergency rooms are usually open on weekdays during usual business hours, so if it ever happens that you have an emergency during the most unlucky time of the day or week, then it can be tricky and painful to locate the nearest emergency room. In this case, it will save you more time if you call an ambulance, but depending on your location, vicinity of the nearest available emergency care can vary.


Free Ambulance service

When you have a medical emergency condition, then, in Japan, you can get a free ambulance service. Now, that's something that comes at a high price in some countries.


No self-prescription please

Okay, I know a lot of people who'd rather take an over-the-counter medicine for a mild ailment, but if you're in Japan, it's not something that you can do. You need to show a doctor's prescription to purchase a medicine.


Language Barrier

There is however one drawback for foreigners. You see, Japanese folk speaks their own language, so if you're staying there but still find it difficult to speak nihongo, it will really be helpful to bring a friend who can interpret for you. But if you're out of friend, don't loose hope, there are clinics and hospitals whose staffs have good command of the english language.


If you get sick and have to go to the hospital or clinic for a consultation with a doctor, you'll know that without an insurance, health care cost can be pricey. In other parts of the world, it is a tragic reality that modern health care has not yet reached them, consequently people die without even seeing a doctor.

Meanwhile in Japan, healthcare is accessible to everyone, from the poor to the riches, from the young to the old, from the employed to the  unemployed.

7 Facts about Keto Diet - Healthbiztips

7 Facts about Keto Diet

Keto or ketosis diet has gained popularity over the last few years. Here are some facts you should know about this diet.

7 Facts about Keto Diet - Healthbiztips

1. When you follow a standard ketogenic diet, you have to cut down your carbohydrate intake to less than 5%.

2. School taught us that we have 3 main energy source -- carbohydrate, protein, and fat. If you remember, it is emphasized that our main energy source should be carbohydrates. We'll, ketogenic diet is a diet that directly opposes that teaching. Instead of getting much of our energy needs from carbohydrates, ketogenic diet focuses on a diet high in fat while keeping carbohydrate intake minimal.

3. Did you know that glucose metabolism promotes inflammation? Whereas, when your body turns to ketones for energy, it helps prevents this damaging inflammatory response.

4. Ketogenic diet is a popular diet to loose weight, prevent and manage inflammatory diseases like Alzheimer's disease, cancer, and cardiovascular disease.

5. Since keto diet limits carbohydrate intake, the body is forced to turn into ketones as an energy source which induces the body into a state of ketosis (high ketones in the blood).

6. Ketogenic diet is claimed to benefit people suffering from diabetes as it brings blood sugar level down, however caution should still be taken to avoid diabetic ketoacidosis. Diabetic ketoacidosis is a medical emergency in which ketone level in the blood reaches a dangerously high level, which turns blood acidic and interferes with the normal functioning of vital internal organs.

7. Ketogenic diet reduces cravings while it increases the amount of time you feel full.

Another good reason to cut on carbohydrate intake is it's positive effect of lowering triglyceride level in the blood. On the other hand, did you know that shifting to a low-fat diet can drastically increase triglyceride level?
