Contents. Testicular cancer. 7.4 × 5.5-cm seminoma in a radical orchiectomy specimen. Testicular cancer is cancer that develops in the testicles, a part of the male reproductive system. [ 2 ] Symptoms may include a lump in the testicle or swelling or pain in the scrotum. [ 2 ] Treatment may result in infertility.
Relative incidences of testicular tumors, showing seminoma at bottom left. [2] A seminoma is a germ cell tumor of the testicle or, more rarely, the mediastinum or other extra-gonadal locations. It is a malignant neoplasm and is one of the most treatable and curable cancers, with a survival rate above 95% if discovered in early stages.
003909. [ edit on Wikidata] Testicular self-examination (TSE) is a procedure where a man examines his own testicles and scrotum for possible lumps or swelling. [ 1 ] It is usually undertaken at home while standing in front of a mirror and after having a warm bath or shower. [ 1 ] Monthly self-examination of the testicles starting at puberty may ...
Endodermal sinus tumor (EST) is a member of the germ cell tumor group of cancers. [1] It is the most common testicular tumor in children under three, [2] and is also known as infantile embryonal carcinoma. This age group has a very good prognosis. In contrast to the pure form typical of infants, adult endodermal sinus tumors are often found in ...
Testicular size as a proportion of body weight varies widely. In the mammalian kingdom, there is a tendency for testicular size to correspond with multiple mates (e.g., harems, polygamy). Production of testicular output sperm and spermatic fluid is also larger in polygamous animals, possibly a spermatogenic competition for survival.
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. [ 2 ][ 7 ] These contrast with benign tumors, which do not spread. [ 7 ] Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. [ 1 ]
These types include: Carcinoma: Cancers derived from epithelial cells. This group includes many of the most common cancers that occur in older adults. Nearly all cancers developing in the breast, prostate, lung, pancreas, and colon are carcinomas. Sarcoma: Cancers arising from connective tissue (i.e. bone, cartilage, fat, nerve), each of which ...
Testicular cancer metastasizes in a predictable pattern, and lymph nodes in the retroperitoneum are typically the first place it lands. [1] [2] By examining the removed lymphatic tissue, a pathologist can determine whether the disease has spread. If no malignant tissue is found, the cancer can be labeled Stage I, limited to the testicle. [3]
