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.
1 Kittens can contract roundworms by nursing from an infested mother. 2  Worm ova can be ingested when a cat uses infested kitty litter and then cleans her paws while grooming. 3  Eating rodents that have roundworms is another way to acquire an infestation. 4  Biting and ingesting fleas can also lead to a case of roundworms.
