Under no circumstances is multiple myeloma contagious. 

While direct invasion by multiple myeloma to the eyes is rare, several ocular complications can arise either from the disease or its treatment. Hypercalcemia, a condition commonly associated with myeloma, can lead to vision disturbances. Moreover, some chemotherapy drugs and steroids, often used in myeloma treatment, can cause cataracts or other eye issues. 

Anemia, a decrease in the number of red blood cells, is a common symptom in patients with multiple myeloma. The disease can interfere with the bone marrow’s ability to adequately produce red blood cells. Additionally, the kidney damage associated with myeloma can reduce the production of erythropoietin, a hormone that stimulates red blood cell production. […]

If lactate dehydrogenase (LDH) levels are elevated in a patient suffering from dysgerminoma, there are a couple of reasons why this might happen. It may be due to a tumor that is larger in size, increased cellular activity or perhaps a positive response to treatment.

Dysgerminoma is a rare type of germ cell tumor that affects the ovaries.

There is no proof of dysgerminoma being a hereditary disease. While it can sometimes affect multiple members of the same family, it usually appears sporadically.

Seminomas and non-seminomas are both types of testicular tumors that originate from germ cells. What makes them different is their behavior, cellular characteristics and how they respond to treatment.

Seminoma is a type of tumor that originates from the germ cells. It mostly affects the testicles, but in some rare cases, it can be found in certain extra-gonadal sites.

Non-seminoma is a tumor that is made up of multiple types of cells and tissues and spreads more quickly than a seminoma. It arises from germ cells just like seminoma but it’s more aggressive and requires a different approach.
