The size of the adrenal glands can be useful in diagnosis, studies have found that the size of the adrenal gland in diabetic cats without hypersomatotropism does not differ significantly from non-diabetic cats; [11] [12] [1] however adrenomegaly is not pathognomonic to hypersomatotropism and can occur with other conditions in cats such as ...
During the luteal phase (latter half) of the menstrual cycle, due to increased mammary blood flow and/or premenstrual fluid retention caused by high circulating concentrations of estrogen and/or progesterone, the breasts temporarily increase in size, and this is experienced by women as fullness, heaviness, swollenness, and a tingling sensation.
The indication is an excess breast weight that exceeds approximately 3% of the total body weight. [3] There are varying definitions of what is considered to be excessive breast tissue, that is the expected breast tissue plus extraordinary breast tissue, ranging from as little as 0.6 kilograms (1.3 lb) up to 2.5 kilograms (5.5 lb) with most physicians defining macromastia as excessive tissue of ...

Hyperplasia of the breast – "Hyperplastic" lesions of the breast include usual ductal hyperplasia, a focal expansion of the number of cells in a terminal breast duct, and atypical ductal hyperplasia, in which a more abnormal pattern of growth is seen, and which is associated with an increased risk of developing breast cancer.
[59] [60] Accordingly, overexpression of COX-2 in mammary gland tissue produces mammary gland hyperplasia as well as precocious mammary gland development in female mice, mirroring the phenotype of VDR knockout mice, and demonstrating a strong stimulatory effect of COX-2, which is downregulated by VDR activation, on the growth of the mammary glands.
Mammary gland tumors are the third common type of cancer in older female cats, with the most common symptom manifesting as a lump in the breast tissue. [3] Domestic short-haired cats and Siamese appear to have a higher incident rates. [10] The tumor is typically firm and nodular, and adheres to the overlying skin. [11]
