What is the difference between cyst and tumor just under skin in dogs?

Cysts and tumors are both abnormal growths that can occur just under the skin in dogs. However, there are some key differences between the two.

Cysts are fluid-filled sacs that are typically benign, meaning they are not cancerous. They can vary in size and shape, and they may be solitary or multiple. Cysts are often caused by a blockage of a sebaceous gland, which is a gland that produces oil to keep the skin moist.

Tumors are solid growths of tissue that can be either benign or malignant (cancerous). Malignant tumors can spread to other parts of the body, while benign tumors do not. Tumors can vary in size, shape, and color, and they may be solitary or multiple.

The following table summarizes the key differences between cysts and tumors:

| Characteristic | Cyst | Tumor |

|---|---|---|

| Definition | Fluid-filled sac | Solid growth of tissue |

| Benign or malignant | Typically benign | Can be either benign or malignant |

| Size and shape | Varies | Varies |

| Solitary or multiple | Can be either | Can be either |

| Cause | Often caused by a blockage of a sebaceous gland | Can be caused by a variety of factors, including genetics, environmental factors, and hormonal imbalances |

If you notice a growth on your dog's skin, it is important to have it checked by a veterinarian to determine whether it is a cyst or a tumor. Your veterinarian will be able to recommend the best course of treatment.
