Human body is made up of organs. An organ is a structure that contains at least two different types of tissues functioning together for a common purpose.  There are many different organs in the body: the liver, kidneys, heart, even your skin is an organ. Tissues are again made up of Cells, the body’s basic unit and the smallest part of an organ. All cancers begin in cells. The body is made up of different types of cells.

To keep the function of the body proper cells grow by dividing and multiplying itself in a controlled way. This is an automatic process and done by the body as they are needed. In a normal process old cells die and they are replaced by new cells. But sometimes due to many reasons the DNA, the primary component of a cell, becomes damaged or changed and produces mutations that hampers the normal division and multiplication of a cell. And then the cells that should die remain alive. The formation of news cells continue even if the body does not need them. Then there is an accumulation of extra cells that forms a mass of tissue known as tumor.

All tumors are not cancers. There are two types of tumor - benign or malignant.

Benign Tumors are non cancerous. They can be removed. Most of the time they are not life threatening and do not spread to other parts of the body.

Malignant tumors are cancerous. In this case Cells have the ability to spread and affect adjacent tissues and organs. Sometimes the cancerous cells enter into the blood stream and spread the disease to other organ. The spread of cancer from one part of the body to another is called metastasis. 

Types of Cancer

Cancer is a group of diseases and there are almost 100 different types of cancers. They are classified by the type of cell that resembles the tumor. The main categories are:

· Carcinoma - cancer that begins in epithelium tissues, the tissues composed of layers of cells which line the cavities and surfaces of structures throughout the body. It is also a type of tissue that forms many glands. The outermost layer of our skin is composed of dead stratified squamous, keratinized epithelial cells. the skin or in tissues that line or cover internal organs.

· Sarcoma - cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.

· Leukemia - cancer that starts in blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood.

· Lymphoma and myeloma - cancers that begin in the cells of the immune system .

Central nervous system cancers - cancers that begin in the tissues of the brain and spinal cord

Have you been wondering for a long time about how to get rid of skin tags? Don’t think you are alone. Lots of people suffer with this problem, but very few people actually know how to get rid of them.

Let’s first understand that a skin tag is only a small piece of skin that protrudes from your body like a plant stalk or a tiny offshoot. They are not a deadly skin related infection nor are they dangerous in any way so don’t get too worried.

If you suspect that you have a skin tag remember that it is not an indication of any kind of infection. Sometimes it can be caused because of a material that you wore. Unless it becomes painful, there is no need for you to worry unnecessarily over it or have it removed.

Remember they can appear anywhere, but they normally tend to appear near the armpit, under the breast, near the neck, eyelid and groin area.

Here are some home remedies that you may want to try:

You can use clear finger nail polish as it is one of the best ways to get rid of skin tags. You have to cover it with finger nail polish and let it stay on till the nail polish dries. Do this at least twice during the day, gradually you will find that it will shrink and completely get weeded out.

Another more drastic way of removing a skin tag is to opt to cut it off. You will need to use a pair of well sterilized scissors or you can also use a pair of disinfected nail clippers to cut it off.

It is good if you can apply a generous amount of alcohol and rub the area where the tag is located. After doing this, snip it from the base using a scissors. As soon as you are done stop the bleeding with an instant application of peroxide and put some pressure on the area also.

Finding the right arthritis specialist is extremely important since arthritis not only can cripple you but it also can significantly shorten lifespan.

I give a lot of talks and the questions I hear a lot are: “I went to an arthritis specialist and they weren’t anything special” or “How do I find a good specialist?”

Let’s make a distinction here… there’s a big difference between an arthritis specialist and an arthritis expert. To get the best results you want an expert!

A specialist is just somebody who passed the board exam. An expert is someone who not only passed the board exam but who has also devoted his or her life to becoming the best in their field. They publish articles, they do research, they are focused on top-notch patient care, and they make it their life’s work to do their best to help people who have arthritis.

And when it comes to your health, you better find someone who is tops! Otherwise you’re wasting your time and money.

1. Board certification. Board certification is no guarantee. However, if a doctor isn’t board certified that should send up a red flag.

2. You want someone who has been in practice at least 20 years. Medicine is like most skills…the more experience a specialist has the better. In 2001, medical errors accounted for 97,000 deaths in the United States and there’s a direct correlation between lack of experience and medical errors.

3. Look for these initials after the MD…

a.F.A.C.P. This stands for Fellow of the American College of Physicians. This means the doctor has academic credentials-they’ve published papers and are respected as an authority.

b.F.A.C.R. This stands for Fellow of the American College of Rheumatology. This means that they are at least board eligible or board certified.

If they don’t have FACP as well as FACR, they’re not an expert.

4. Arthroscopy is an important skill. It’s the ability to look inside the joint with a small telescope and diagnosis and treat. Ask if the arthritis specialist is a member of the Arthroscopy Association of North America? These are the most skilled arthroscopists in the world.

5. Do they have in-house laboratory, x-ray and bone density equipment? If they do, ask if their lab is high complexity and certified by the state as a reference lab.

6. Do they have diagnostic ultrasound? This is a new technology for visualizing joint disease. It is used to detect evidence of early inflammation and also to follow the effects of medications in slowing the disease process. The use of diagnostic ultrasound allows the physician to perform joint injections with 100% accuracy. Diagnostic ultrasound is also much less expensive than magnetic resonance imaging (MRI).

7. They should have completed at least 100 clinical research studies. Physicians who have extensive clinical research experience are much more attuned to the latest therapies than those specialists who don’t perform clinical research.

8. A specialist should have published at least 50 papers in the medical literature.

9. How many Google citations does the expert have? Nowadays, more and more people are getting their information from the Internet. The mega search engine, Google, probably has the best ability to search for experts. The number of citations a doctor has tells you how much he or she has invested in time and effort to help with patient education and further their specialty. It stands to reason, the more they write the more knowledge and expertise they possess. To see how many citations they have, just go to Google, put in the expert’s name in quotes, like this, “nathan wei” and then the word “arthritis”, so it looks like this…

“nathan wei” arthritis.

If you get fewer than 500 citations, that person is not an expert. Remember, not all specialists are experts. It’s like any profession. There are good ones, there are bad ones, and there are truly great ones. In fact, there are doctors who are pretty terrible. That’s right. They’re terrible. Why? Because they don’t know their specialty and they don’t have good patient skills. Do you really want to be stuck with a lemon? If you have arthritis, a potentially life-changing disease, don’t you think it’s best to see an expert?

10.What is their staff like? Even a great physician needs a great support staff.

11.Do you get the feeling they care? A good practice will make you feel like family.

12.Are they part of your insurance plan? This is a trick question. The very best experts don’t let their decisions get made by the insurance company. Your health is the most important
