Cat Cancer Lumps
Lumps and bumps will appear on or under the skin of most senior cats. Most of these are benign and are no cause for concern. If however, your cat has a new lump, you should consult with your veterinarian before making a decision. The bump needs to be evaluated. Your vet can examine the lump and do the necessary tests to determine if it is a malignant tumor.
Types of Cancer Lumps
There are several different types of cancer lumps that may appear on your cat.
Lymphomas Lymphomas can appear under the skin in the lymph nodes, in the liver, spleen and other organs, and can lead to Cat Lymphoma Cancer. The internal lumps are felt upon examination by your vet. Those that involve lymph nodes will often appear as lumps under the skin. Some of the tumors in the lymph nodes cause no symptoms. Others can cause itching, swelling, ulcers and redness. Normal treatment is removal of the lump.
Sarcoma There are two basic types of sarcomas, fibrosarcoma and hemangiosarcoma. Both are aggressive and are either on the skin or directly under it. They are aggressive tumors and can spread very quickly. Removal of the tumor can include amputation at times.
Hemangiosarcoma are those that appear on the chest or abdomen and are related to sun exposure. These are dark tumors and often will ulcerate. An example of this is Cat Bone Hemangiosarcoma.
Fibrosarcomas are seen around injections sites of medication or vaccination. They will appear as firm lumps that vary in shape. One example is [Cat Skin Fibrosarcoma].
Mast Cell Tumor
The appearance of a mast cell tumor is not uncommon. They may vary in size and shape and can also vary in the number of tumors. This is one of the types of tumors that are graded. The grade can vary from one to four with level one being a slow growing tumor and level four fast and potentially able to metastasize. Success of the treatment depends on the stage of the mast cell.
Squamous Cell Carcinoma
Cat Squamous Cell Carcinoma is also quite common. These are specifically associated with sun damage or skin conditions. There are two possible ways they can appear. They can appear as cauliflower-shaped lesions. These usually ulcerate and are usually present on the face or as scaly, crusty ulcerations on the legs or other parts of the body that have been irritated frequently. Radiation or surgery are the two most common types of treatment for this type of cancer. Most treatment will depend on the location.
Basal Cell tumors
This type of tumor can be malignant or benign. As with any other tumor, Cat Basal Cell Tumor should arouse some concern in the cat owner. They will usually appear on the head, chest or neck. Occasionally they are soft and fluid filled, but can also be firm and dark in color. Basal cell tumors seldom metastasize and can be removed surgically without Cat Cancer Chemotherapy in most instances.
Histiocytosis can be present in one of three forms. While only one is malignant, it is important to have it checked. It appears as a large nodule that is hairless. In most instances there will be ulcers associated with them. The malignant histiocytosis can affect the internal organs and the skin and there is no effective treatment for them.
