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.
Another way to tell if your cat has come across a worm infestation is to monitor their feces. Certain types of worms will remain visible in the feces; other types may not be visible, but will cause bleeding in the stool. Consistent dark tarry stools or diarrhea may also be signs of worms in the intestines.
