What are the different type of cancer

Defining cancer
Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start -- for example, cancer that begins in the colon is called colon cancer; cancer that begins in basal cells of the skin is called basal cell carcinoma.
Cancer types can be grouped into broader categories. The main categories of cancer include:
Carcinoma - cancer that begins in 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.

Origins of cancer
All cancers begin in cells, the body's basic unit of life. To understand cancer, it's helpful to know what happens when normal cells become cancer cells.
The body is made up of many types of cells. These cells grow and divide in a controlled way to produce more cells as they are needed to keep the body healthy. When cells become old or damaged, they die and are replaced with new cells.
However, sometimes this orderly process goes wrong. The genetic material (DNA) of a cell can become damaged or changed, producing mutations that affect normal cell growth and division. When this happens, cells do not die when they should and new cells form when the body does not need them. The extra cells may form a mass of tissue called a tumor.

Natural Cancer Treatment

If you're reading this, you're probably looking for answers, just like I was a while back. It was almost as if I had a sense that the answers must be out there somewhere and I was guided to find them.

I felt that if I looked hard enough, I'd find the missing links, the overlooked miracles, the plants and herbs provided by nature to help us heal. I cross checked sources of information and ploughed through everything on alternative cancer treatment that I could find. Even employing a team of researchers to gather information with me. We came up with 350 alternative cancer treatments, surprising even ourselves. It is the most comprehensive collection you will find anywhere in the world today.

Every one of the 350 alternative treatments gave us an 'Aha!' moment, as I am sure it will you. Whether you're looking to find out more about alternative cancer treatment for yourself, or on behalf of a loved one, my comprehensive guide has been designed to satisfy your quest for answers.

I know how powerless it feels, not knowing what the future holds. I had so many questions. As I searched for information on both conventional and alternative cancer treatments, I was shocked to find how so many alternative cancer treatments had been lost to public knowledge, or discredited, or forced underground.

You must make up your own mind about alternative cancer treatment but I sincerely urge you to own your own health and not hand it over to someone else to own. There is no-one on the face of the earth with more interest in your well-being than you yourself. You must take control of your own destiny and not leave it to others who have their own vested interests!

Tea's Anti-Cancer Powers Affirmed and Expanded in USDA Study

Black and Green Teas Fight Cancer

A team of American and South Korean researchers conducted cell studies that shed new light on the relative anti-cancer properties of green and black tea.

The evidence collected to date suggested that tea's proven anti-cancer powers stem primarily from its powerfully antioxidant flavonoid-type polyphenols.

Thus, it’s been assumed that green and white tea must be the most powerfully anti-cancer forms of the ancient beverage, since they contains more flavonoid-type polyphenols than black tea does.

While black tea (green tea oxidized by fermentation) contains between 3 and 10 percent water-soluble polyphenols by volume, green tea boasts ten times that concentration.

However, as we will see, polyphenols make up only part of the solids in tea: and they may not be the sole or sufficient explanation for tea’s well-documented anti-cancer properties.

And green and black teas also contain different types and proportions of polyphenols.

When tea leaves ferment long enough to turn them black via oxidation, the majority of their catechin-class flavonoid polyphenols change into tannin-like flavonoids called theaflavins and theanine.

However, some population studies have suggested that black tea is as or more protective against certain cancers (including certain breast tumors) as green tea.

Tea flavonoids do five things that work together to stop cancer in its early stages:

1. Cause programmed “suicide” (apoptosis) among cancer cells.
2. Block P450 enzymes, which activate pro-cancer compounds.
3. Stop tumor-promoting chemical signals from cancer cells.
4. Disable damaged, cancer-promoting DNA
5. Block growth of new blood vessels in the tumor (angiogenesis)

Given this context, the general thrust of what the USDA team found came as no big surprise.

But their unexpected findings vis a vis the effects of tea flavonoids on human cancer cells is sure to send scientists back to the bench for further exploration.

Black and green tea work equally well; Benefits not tied tightly to flavonoid content

The joint USDA/South Korea team examined the ability of nine green tea catechins, three black tea theaflavins, and theanine from black tea to induce cell death (apoptosis) in isolated human cancer cells (Friedman M et al 2006).

Tea, berries, and other polyphenol-rich plants are considered key anti-cancer agents because they undermine cancer when it is most vulnerable: during its early, so-called “promotion” stage.

The researchers reported that most of the flavanol-type flavonoids in both green and black tea -- catechins, theaflavins, and theanine – cut the numbers of cancerous human breast, colon, liver, and prostate cells, without big differences among them.

However the efficacy of each different extract of black or green tea tested depended not on its flavonoid content, but simply on the sheer amount of dissolved solids per volume of liquid, regardless of their flavonoid content.

This suggests that something about the non-flavonoid compounds play key roles, and that therefore, black tea may offer anti-cancer benefits closer to those of green and white tea than thought.

They also found that ethanol/water extracts of tea possess more flavonoids and are more potently anti-cancer, suggesting that tea supplements (mostly made this way) may have a bit of an edge over water extracts, such as plain cups of tea. But any hypothetical anti-tumor advantage supplemental tea capsules might offer is likely to be quite expensive, compared with enjoying tea by the cup.

As the USDA/Korea team said (Friedman M et al 2006), their findings extend our knowledge of the anti-cancer potential of tea, and suggest, most significantly, “… that consumers may benefit more by drinking both green and black teas.”

Brain Tumors Claim More Children's Lives than Any Other Type of Cancer

Brain Tumors Claim More Children's Lives than Any Other Type of Cancer

By Dr. Ben Kim

The headline is correct - brain tumors now claim more children's lives than any other type of cancer. There aren't any published studies in the medical literature that all epidemiologists can point to and offer as proof that regular use of a cell phone can increase a child's risk of developing a brain tumor. And there never will be such a study, as definitive proof in the research world requires a double-blind, randomized control trial; how can you conduct a trial in which you ask a group of children to use a cell phone for 'x' number of hours per week?

If you know any children who regularly have a cell phone pressed up against their heads, please have them and their parents view the following special report from Australia, featuring Dr. Charlie Teo:


The bottom line is this: pressing a cell phone up against our skulls on a regular basis is an unnecessary risk for abnormal cellular growth in the brain and brain stem region. And the risk is greater for children, whose cells are growing and multiplying more rapidly than they ever will.

The department of public health in Toronto, Ontario is now recommending that young children and teenagers limit their use of cell phones to avoid potential health risks - it's the first advisory of its kind in Canada that takes into account the known and unknown dangers of regular, long term exposure to electromagnetic fields. The official recommendation is that children under eight limit their use of cell phones to emergencies, and that teenagers limit their calls to 10 minutes or less.

A good rule that parents can establish is that phone calls that occur while at home must be on a land-line. And it's best that all cordless phones be replaced with corded phones, as some cordless phones give off as much electromagnetic energy as some cell phones.

If you need help convincing teenage children of the potential dangers of regular cell phone use, you might consider getting a Gauss meter like the Cell Sensor EMF Detector. Holding a Gauss meter up against cell phones, cordless phones, electrical appliances, and electrical outlets is an effective way to demonstrate the presence of electromagnetic fields.

Cancer Information

The list of common cancer types includes cancers that are diagnosed with the greatest frequency in the United States. Cancer incidence statistics from the American Cancer Society and other resources were used to create the list. To qualify as a common cancer, the estimated annual incidence for 2007 had to be 30,000 cases or more.

The most common type of cancer on the list is non-melanoma skin cancer, with more than 1,000,000 new cases expected in the United States in 2007. Non-melanoma skin cancers represent about half of all cancers diagnosed in this country.

The cancer on the list with the lowest incidence is thyroid cancer. The estimated number of new cases of thyroid cancer for 2007 is 33,550.

Because colon and rectal cancers are often referred to as "colorectal cancers," these two cancer types were combined for the list. For 2007, the estimated number of new cases of colon cancer is 112,340, and the estimated number of new cases of rectal cancer is 41,420.

Kidney cancers can be divided into two major groups, renal parenchyma cancers and renal pelvis cancers. Approximately 85 percent of kidney cancers develop in the renal parenchyma,² and nearly all of these cancers are renal cell cancers. The estimated number of new cases of renal cell cancer for 2007 is 43,512.

Leukemia as a cancer type includes acute lymphoblastic (or lymphoid) leukemia, chronic lymphocytic leukemia, acute myeloid leukemia, chronic myelogenous (or myeloid) leukemia, and other forms of leukemia. It is estimated that more than 44,000 new cases of leukemia will be diagnosed in the United States in 2007, with chronic lymphocytic leukemia being the most common type (approximately 15,000 new cases).

The following table gives the estimated numbers of new cases and deaths for each common cancer type:

Cancer Type	Estimated New Cases	Estimated Deaths
Bladder	67,160	13,750
Breast (Female -- Male)	178,480 -- 2,030	40,460 -- 450
Colon and Rectal (Combined)	153,760	52,180
Endometrial	39,080	7,400
Kidney (Renal Cell) Cancer	43,512	10,957
