The first thing to consider tumour arising in the pituitary gland, as this gland controls most other endocrine glands (adrenal, thyroid and parathyroid glands, pancreas, hypothalamus).
Given that cancer as a malignant tumor often reappears from benign tumors, consider how it appears on the hand.

On somatotropinoma - pituitary tumors, manifested by increased secretion of growth hormone (and subsequently gigantism, acromegaly), indicates the line of the Turkish saddle, which crosses the line of fate in the broken line of the head.
Growth hormone somatropin causes growth of the body, accelerates the growth of tubular bones of the extremities; affects thyroid, pancreas, reinforcing the latter and the reinforcing effect of insulin. When an excessively elevated level of growth hormone can lead to decreased production of insulin and, consequently, to diabetes.
Thick line Turcica develops due to pituitary tumors caused by hormonal drugs, head injuries and diseases such as meningoencephalitis or arachnoiditis.
On kortikotropinom - adenoma of the pituitary, manifested by increased secretion of adrenocorticotropin (ACTH), (causes the disease, Cushing's syndrome, Nelson) - indicates a point on the line of fate (hypophysis) or the island is oval shaped in a large triangle (2), and also the line of fate, branched before the line of head indicates a dysfunction of the pituitary gland, leading to endocrine diseases (1).

Kortikotropinom is found in approximately 10% of cases of pituitary adenomas and is manifested by deposition of fat in the shoulders, neck, face, hypertension, osteoporosis. Further, women experience hair growth on the face, back and chest, stretch marks on the skin of the abdomen, back and thighs and buttocks, while men on the back.

The hormone ACTH causes to produce corticosteroids in the adrenal cortex, particularly cortisol. Production of ACTH is increased in stressful situations (especially winter swimming, cold water to quench), which leads to the release of huge amounts of energy. Unused energy leads to increase melanin production, which manifests itself in the form of dark pigmentation on the skin. Subsequently, these spots may transform into a cancer cell.
On prolactinoma - adenoma of the pituitary gland, manifested increased secretion of prolactin, yueyue circle ring on the line of fate in his right hand. Found in approximately 30% of cases of pituitary adenomas. The increase in prolactin levels accompanied by a decrease in estrogen in women and testosterone in men, which may lead to enlarged Breasts, reduced sexual drive, disruption of menstrual cycle, and subsequently, to failure of the ovaries, uterine fibroids and infertility.

Prolactin levels is investigated in amenorrhea - absence of menstruation, gynecomastia - enlargement of Breasts in men for suspected pituitary tumor, the tumor or breast cancer.A constant flow of milk from the breast in combination with amenorrhea may indicate a pituitary tumor.
Thyrotropinoma - pituitary tumors, manifested by increased secretion of thyroid-stimulating hormone (TSH; thyrotropin), causing secondary hyperthyroidism - is displayed as a point on the line of fate in his right hand (in a big triangle formed by the line head, life and health).

Increasing levels of thyrotropin is found in primary hypothyroidism (reduced thyroid function) and quite rare (2-3% of cases, adenomas of pituitary) - pituitary tumors - thyrotropinoma.

The line crosses the line of fate (hypophysis) in the big triangle indicates a head injury.
Thick line indicates the pituitary gland to increase pituitary caused by a tumor (as Valery Zolotukhin), disease of the thyroid gland or the gonads.
