The Genetic origins of the Cancers


Many people think of cancer as a single disease, however, it actually results from more than 1,000 different disorders in normal cell and tissue function. All cancers have one feature in common: They all are diseases of uncontrolled cell division. For healthy people, the body regulates the production of new cells very precisely. But in cancer patients, gene mutation lead to breakdowns in the cell communication and growth control normal in healthy cells. Out of the normal control, cancer cells can become invasive and spread to other parts of the body. As a consequence, normal tissue and organ functions may be seriously disrupted.

Mutation in two main groups genes are closely related with cancers:

A: Proto-oncogenes, which encode for proteins important for normal cell behavior including proliferation, differentiation and survival. Proto-oncogenes will be converted to ongogenes by the change in gene structure, location, or function. At this stage, the proto-oncogenes become into the oncogenes.

Oncogens can be categorized to the following groups:
  • Growth Factors: COLIA1-PDGFB, PDGF etc.
  • Receptors: v-erb-b, EGF-receptor etc.
  • Plasma membrane GTP-binding proteins: KRAS, Ras etc.
  • Nonreceptor protein kinases: BRAF, Raf kinase etc.
  • Transcription factors: MYC, v-jun, V-fos etc.
  • Cell-cycle or cell-death regulators: CYCD1, CDK4 and BLC2
B: Tumor Suppressors: Tumor suppressor genes encode for proteins that regulate cell survival and slow or stop cell proliferation.  Cells with mutation in these genes, will ignore signals that direct them to apoptosis.
 Examples of tumor suppressor genes: APC, BRCA1, BRCA2, SMAD4, NF-1, NF-2, CDKN2A, p53, RB, HL and WF1.

Panic attack or heart attack?

The symptoms of a panic attack appear suddenly, without any apparent cause. They may include: racing or pounding heartbeat; chest pains; stomach upset; dizziness, lightheadedness, nausea, difficulty breathing; tingling or numbness in the hands; hot flashes or chills; trembling and shaking; dreamlike sensations; terror and fear of dying.

Panic attacks may be symptoms of an anxiety disorder. These attacks are a serious health problem in the U.S. At least 20% of adult Americans, or about 60 million people, will suffer from panic attacks at some point in their lives. About 1.7% of adult Americans, or about 3 million people, will have full-blown panic disorder at some time in their lives, twice as often for women than men.

Its symptoms can closely mimic those of a heart attack. So if you do not have heart disease history and you are young (especially the teenagers) for suffer the hear attack, and you live in some sort of stress. You are most likely experiencing the anxiety disorder.

In this situation, first adjusting your home dishes, especially taking more vitamin B complex, banana (supply sodium ion) etc. will help; second, try to release your stress, change work or study environment etc.Taking medicine is not always the first choice, which will make you more dependent on the medicine; some people have to take the medicine over his/her life time.

Pesticide exposure, a public problem to be overlooked.

As it states, pesticides "…on our food, even after washing; …in our bodies, for years; …& in our environment, traveling many miles on wind, water and dust."

Even we produce all vegetables and fruits in our own little garden, we may not be able to avoid pestticides because of the water we used and dust we "received".

How much is too much? Here is the resource.

An inexpensive but very important fruit we can not overlook!

Banana, a very common and inexpensive fruit that almost everybody can afford to eat everyday. It may not be delicious as some other costly fruits, but it is essential to our health.

Some people with anxiety or depression may experience like this: At specific time each day, her or his heart beats over 120 per min. Usually they would call 911 at this situation. However after examination in the emergency room or the hospital, he or she would be told that he or she is healthy, no any signs of heart attack! But her or his experience a few minutes ago is scaring! The truth is: she or he does not have heart attack. Think about, how does a heart attach occur at a specific time each day?

But how come? People can consult their doctors about the reasons caused by anxiety.

Sometimes, the doctors would recommend eating more banana. Why? Because she or he is lack of potassium, which is important to the heart pump and rich in banana. Meanwhile, banana also contains element zinc, which is important to improve our body's defense system.

So, do not look down the inexpensive fruit. It is cheap but works well.

Stress: the killer of happiness

When people are living under pressure too long without release, in the end he or she might be depressed.

When people often feel blue, or often see the negative of life, or are down very easily, he or she is most likely under stress or with anxiety.

When depressed, people easily feel hopeless, sad, or helpless, or lose control. Nothing seems to be good or beautiful in the world.

When seeing a doctor, people might be recommended using some medicines. But be careful that people may get dependence on them and be never able to get rid of it.

To reduce the stress, the first thing is to get rid of the sources: the pressure.

Be away from the pressure if possible.Seek positive feedbacks, support, and encouragement from family and friends.
If like music, listen to happy music instead of sad melody.
If possible, find a person you trust to tell our feeling and our story. We need release something from our mind and  our heart. If not, go somewhere and yell or shout to the nature.
If like travel, go to the nature instead of crowd city.
If like excersie, make sweat ourselves and take a hot shower afterwards.
If like movies, watch those with happy and beautiful stories instead of tragety or violence or advanture.

Avoid alone although tempered.

Most important, try to do what we like or interest instead of something demanding too much.
Life is not easy in modern society, we have to take care of ourselves.
