Fibrosarcoma is a medical condition which is uncommon and occurs due to a tumor in the knee which produces a collagen matrix and can cause pain and swelling. Adults between 30 and 60 years usually get it.

The survival rate due to surgery is very good - over 95%. However, the survival rate for fibrosarcoma is pretty dismal as these are aggressive tumors that are often not diagnosed until they are extensive and have metastasized.

Aluminum is a common adjuvant for injectable vaccines for animals and humans and is added to the vaccine because it helps stimulate the immune system to react against the vaccine and build a stronger immune response with fewer booster vaccinations. A fibrosarcoma is a malignant, often aggressively invasive tumor that arise from fibrous connective tissue, which is what forms scar tissue. There is a hypothesis that administration of a vaccine with an aluminum adjuvant can cause overstimulation of the fibrous scar tissue response which then results in the development of a fibrosarcoma.

Cats in particular seem to be sensitive to this and about 1 in 10,000 cats will develop a fibrosarcoma in response to a vaccination.

My cat is dealing with fibrosarcoma so I did not want to tax his systems further with flea poisons. A local pet store - Phydeaux in Raleigh - told me about Diatomaceous Clay - tough to spell but great to use. This clay dehydrates the fleas and ticks and is totally benign. You can use it on your kitchen counters for ants, anywhere.

I just rubbed it into Smokey's fur - he purred the entire time. You do need to repeat it weekly. You also could dust your carpets and floors with it to get the population down. I would dust one day and vacuum two days later and redust until the population is not noticeable then I would do it weekly.

Hope this helps.

Sarcoma (for examp. Langerhern Cell Sarcoma, Sarcoma of Ewing).

addition! Reticulosarcoma (means sarcoma of the reticulocyte cells)

A malignant tumor of connective tissue is called Sarcoma.

There are three different subcategories: Hard Tissue Sarcomas (can occur in bone or cartilage), Soft Tissue Sarcomas (can occur in muscles, tendons, or lymphatic vessels) , and Liquid Tissue Sarcomas (can occur in blood and lymph)
