Thyroid cancer is a fairly common malignancy which can occur in any age group especially in people who have had radiation therapy in the neck area, although it is most common after age 30 and its aggressiveness increases significantly in older patients. Thyroid cancer develops in your thyroid, a butterfly-shaped gland located at the base of your neck, just below your Adam's apple.
Types of Thyroid Cancer Thyroid cancers are divided into papillary carcinomas, follicular carcinomas, medullary thyroid carcinomas (MTCs), anaplastic carcinomas, primary thyroid lymphomas, and primary thyroid sarcomas.
Papillary tumours account for half of all thyroid cancers in adults, it is most common in young adult females. Follicular carcinomas are less common but more likely to recur and metastasize to the regional nodes and through blood vessels into the bones, liver and lungs. Medullary carcinoma is a rare familial cancer which is completely curable if detected before it causes symptoms. The least common type of thyroid cancer is anaplastic which has a very poor prognosis. Anaplastic thyroid cancer tends to be found after it has spread and is not cured in most cases
Causes of Thyroid Cancer Predisposing factors include; radiation exposure, prolonged thyroid stimulating hormone exposure, familial predisposition and chronic goiter.
Signs and Symptoms The primary signs of thyroid tumors are: a painless nodule, a lump or swelling in the neck sometimes growing rapidly, a pain in the front of the neck sometimes going up to the ears, hoarseness or other voice changes that do not go away, trouble swallowing, breathing problems, a cough that continues and is not due to a cold.
Diagnosis The first clue is usually an enlarged palpable nodule in the thyroid gland, neck, lymph nodes of the neck, or vocal chords. Tests must rule out non malignant thyroid enlargements which are much more common. Thyroid scans measure the ability of the nodules to trap isotopes in comparison to the rest of the thyroid. Other tests include CT scans, biopsy and ultrasonic scans.
Treatment Treatment options may include surgery to remove the thyroid gland and nearby lymph nodes, chemotherapy, radiation therapy and hormone therapy. Anaplastic cancer patients often require a tracheostomy during the treatment and treatment is much more aggressive than for other types of thyroid cancer.
Radioactive Iodine is given to the patient with thyroid cancer after their cancer has been removed because if there are any thyroid cancer cells remaining in the body then these cells will absorb and concentrate the radioactive poisonous iodine.
Prognosis The survival rate for patients with papillary tumors which have not spread is excellent. Medullary cancer of the thyroid is significantly less common, but has a worse prognosis.

Testicular Cancer - Causes, Symptoms, Treatment and Prognosis | breast cancer husband
Testicular cancer occurs most often in men between the ages of 20 and 39, and is the most common form of solid tumour in men between the ages of 15 and 34. It may also occur in young boys, but only about 3% of all testicular cancer is found in this group. Tumors usually occur in one testicle, however, 2-3% of tumors can occur in both testicles, either simultaneously or at a later date. Tumors can also spread to the lymph nodes, the lungs or other organs. It is more common among Caucasians than among men of African and Asian descent.
Causes Although the exact cause of testicular cancer is unknown, several factors seem to increase risk. These include a past medical history of undescended testicle(s), abnormal testicular development, Klinefelter's syndrome (a sex chromosome disorder that may be characterized by low levels of male hormones, sterility, development of breasts, and small testes), men whose mothers used diethylstilbestrol during pregnancy, or men who have had previous testicular cancer. There is no link between vasectomy and elevated risk of testicular cancer.
Signs and Symptoms The first sign is usually a firm, painless, smooth testicular mass which is sometimes accompanied by a feeling of heaviness in the testicles. Other symptoms of testicular cancer include: a feeling of swelling in the scrotum, discomfort or pain in the scrotum, ache in the lower back, pelvis or groin area, collection of fluid in the scrotum, gynecomastia and nipple tenderness. In advanced stages symptoms include: ureteral obstruction, abdominal mass, coughing, shortness of breath, weight loss, fatigue, pallor and lethargy.
Treatment Testicular carcinoma can be treated with surgery, radiation therapy, chemotherapy, surveillance, or a combination of these treatments. Testicular cancer may be more difficult to treat if it has spread to the liver, bones, or brain, but even in those cases, men can often be cured. If the cancer is a recurrence of a previous tumour, the treatment usually consists of chemotherapy using combinations of different medications, such as ifosfamide, cisplatin, etoposide, or vinblastine, sometimes followed by an autologous bone marrow or peripheral stem-cell transplant.
While it may be possible, in some cases, to remove testicular cancer tumors from a testis while leaving the testis functional, this is almost never done, as more than 95% of testicular tumors are malignant. Usually the scrotum is not removed so that prosthesis can be put in place. Hormone replacement therapy may be needed after bilateral orchiectomy (removal of both testes). Treatment for this condition does not normally affect sexuality, masculinity or erectile function.
Prognosis Testicular cancer has one of the highest cure rates of all cancers: in excess of 90%; essentially 100% if it has not metastasized. Less than five percent of those who have testicular cancer will have it again in the remaining testis.
