For example, benign tumors are mostly well differentiated and malignant tumors are often undifferentiated. However, undifferentiated benign tumors and differentiated malignant tumors can occur. Although benign tumors generally grow slowly, cases of fast growing benign tumors have also been documented.Some malignant tumors are mostly non-metastatic such as in the case of basal cell carcinoma.lso, benign tumors generally have a slower growth rate than malignant tumors and the tumor cells are usually more differentiated (cells have normal features).
How a kitten contracts a worm depends on the type of worm it is. Roundworms and hookworms can be contracted by sharing a litter box with an infected cat. He can also get roundworms from his mother's milk if she was infected. Tapeworms have to be ingested, usually via a flea or rodent that was infected with tapeworms.
Because of this, hookworms can be fatal if left untreated. Fatalities are most common in young kittens. Ancylostoma hookworms are small, thread-like parasites that attach to the walls of the small intestine in cats, feeding on the blood of their host. Both Ancylostoma tubaeforme and Ancylostoma ceylanicum worms are known to invade cats. Hookworms are fairly common, infecting an estimated 10 to 60 percent of all cats at some point in their lives.
