Cancer is named from the place it originates. This makes a difference on what type of treatments will be effective. Being diagnosed with cancer of the unknown primary (CUP) means that cancer has been found in the body but the place of origin is unknown.

If later, the place of origin is found then the type of cancer diagnosis changes from an unknown primary to the specific organ or body area that the disease first began.

Some cases of cancer of the unknown primary are unfortunately never found. Physicians will then decide on the best course of treatment based on two factors: The way the cells look under the microscope and which organs are currently involved.

Statistics and Prognosis:

The exact number of cases of this disease is not known. It may be about 2% to 5% of all cancers in the United States. It is found more often among men than among women. The average age of people with this cancer is about 60 years.

This is a very dangerous cancer. Only half of patients will live 9 to 12 months after their cancer is found. There are several reasons why this cancer is so serious. First, most of these are fast-spreading cancers. Second, because the exact type is not known, it is harder for doctors to know what treatment is best. Also, the cancer is often widespread, making it harder to cure.

In recent years, microscopic and other diagnostic techniques have improved dramatically. For this reason, doctors can now determine the primary site in about four out of five cases.

We're still basking in the hot sun, bronzing our bodies in tanning beds, and playing outdoors without slathering on the sunscreen. What will it take, I wonder, for our society to catch on, to take real steps toward preventing skin cancer?

It seems education isn't enough. Most of us know by now all it takes is one bad sunburn to increase our risk of skin cancer, yet we continue to collect burn after burn after burn. Perhaps like all habit-forming behaviors -- think smoking -- it takes something tragic in our lives to inspire change. When someone we know gets lung cancer after a lifetime of smoking or someone we know develops melanoma after years of sunbathing, maybe we get the hint. Maybe

Now, I know you don't personally know this young woman -- she calls herself Miss Melanoma -- but I suggest you read her story. And I recommend you take what happened to her -- she lost part of her foot to melanoma and is currently battling a spread of the disease -- and allow it to really sink in, allow it to motivate you to take cover from the sun, before something like this happens to you. Because it can.

Rhabdomyosarcoma is a type of soft tissue cancer that is most often found in children. This cancer will usually present itself as a noticeable lump. Since this is a cancer made up of cells that normally develop into skeletal muscles, the lump can appear in different locations of the body. Although most of our skeletal muscles are in our limbs and truck, it is usually found elsewhere.

The most common sites that rhabdomyosarcoma tumors are found:

• Head and Neck (30%-40%)
• Urinary and Reproductive Organs (20%-25%)
• Arms and Legs (18%-20%)
• Truck (7%)

There are two main types of rhabdomyosarcomas that occur in children, embryonal rhabdomyosarcoma and alveolar rhabdomyosarcoma. The embryonal type (ERMS) is the most common type and usually occurs in infants and young children. The alveolar type (ARMS) usually effects older children and teenagers. Embryonal has a better prognosis than alveolar, which is a more aggressive tumor type.

About 3 percent of childhood cancers are diagnosed as rhabdomyosarcoma. In the United States about 350 new cases arise each year. It is the most common type of sarcoma occurring in the soft tissues, which is tissue that lies between the skin and the bone. It is the sixth most common cancer in children.

The researchers say there are no known environmental risk factors that cause rhabdomyosarcoma. There are some inherited conditions that can increase the risk of developing rhabdomyosarcoma but these are only a small fraction of those diagnosed. L-Fraumeni syndrome, Beckwith-Wiedemann syndrome, neurofibromatosis and Costello syndrome are inherited conditions that are known to lead to different forms of cancer. This information gives the researchers of this disease some key knowledge in understanding the disease and points them in the direction of a genetic cause for this type of cancer.

Just two months after her mother lost her battle with gall bladder cancer, Liane was diagnosed with breast cancer. It all happened earlier this year -- and while Liane is still mourning the loss of her mother, she is also still managing the madness of her own disease. Liane is surviving with courage, with determination, with the same powerful spirit that powered her mother's fight.

Liane lives in a small city -- population 43,000 -- in northern Alberta Canada. She has been happily married for 18 years and has two daughters, ages 13 and 15, and a golden retriever named Sunny. Liane loves to garden, cook, read, and spend time with family. She normally works full-time in a real estate and property management office but has been blessed with six months off for treatment. Liane is already -- without a doubt -- a survivor.

Lynne began her blog on August 6 -- one week ago and two months after she endured surgery to clear a clogged bile duct and received the grim and frightening diagnosis of gallbladder cancer. Her cancer is stage IV -- not an uncommon staging for a hard-to-detect disease that many will only survive for two to six months. So Lynne is scared but still strong and hopeful and full of faith. Her goal is to live -- not die -- with cancer, even though her days may be numbered. So Lynne blogs her thoughts and fears and all the bits and pieces of information she gathers about a disease that is rare and resources that are scare. It helps her. And it will surely help others. And here is a glimpse into what she shared in her first post.

If you had only six months or a year to live, would you want to know? What would you do with the information? Would it make a difference in how you lived your life? These are questions I have been asking for the past two months. In asking them, I have also noticed how little guidance there is for this process. Who have I known personally who was able to anticipate their death? I can think of only two individuals, and I never asked them whether or not they were living differently in their awareness of their mortality.

So, those are the themes in this blog. I look forward to a dialog with those I know, and those I don't about this strange, life changing journey.

To Lynne -- and to all others who are faced with the disease -- may you find peace and comfort and strength in every step you take, every direction you follow, every path that becomes your road to recovery.

After I was diagnosed with Stage IIa breast cancer one of the things I did was go crazy with searching, searching and more searching on the internet. What was I searching for? I'll tell you. I was searching for some prognostic information that said that I was definitely going to survive. Guess what? I didn't find what I was searching for.

Some prognostic information for my stage of disease sounded great to me, other things I read were not so great. So what did I do? I printed out the ones that sounded great, of course.

I did find in my searching a prognostic indicator that I was not aware of -- one that wasn't mentioned by my oncologist. The prognostic indicator I found is called the Nottingham Prognostic Index (NPI). NPI has been around since 1992. It can give physicians a guide to see if chemotherapy is warranted just like how the staging system is used. This prognostic indicator takes into consideration the size of the tumor, the nodal status and also the grade of the tumor. This information is plugged into a calculation using all three factors.
