Both benign (non-cancerous) and malignant (cancerous) tumor can also palmar hyperhidrosis.

Causes
Sweaty palms are the result of the overactivation ofeccrine sweat glands.
Eccine sweat glands are those situated in the palms of the hand and soles of the feet.
Palmar hyperhidrosis is almost invariably bilateral (affecting both hands or feet).
Acute vs. Palmar can also bechronic(persistent or recurrent), typically associated with an underlying chronic health condition.
It can also be due to gene mutations inherited from your parents that cause excessive sweating.
Strong emotions can trigger the sudden release of acetylcholine into the bloodstream.
This, in turn, overexcites postganglionic nerves, causing the spontaneous release of sweat.
The sweating may continue until the acute stress is eased.
Endocrine Causes
Theendocrine systemis responsible for the regulation of hormones in the body.
Acetylcholine is a neurotransmitter produced by the brain that acts as an endocrine hormone.
Certain disorders can cause hormonal imbalances that lead to the overproduction of acetylcholine.
These can manifest with a host of other physiological abnormalities, including palmar hyperhidrosis.
With that said, fever tends to cause a drop in acetylcholine levels.
The risk of palmar hyperhidrosis is sometimes dose-dependent, occurring when doses are high or when drugs are abused.
There are a number of treatment options.
Stress and anxiety can cause you to sweat, which may exacerbate the problem.
In addition to medical treatments, psychotherapy is often recommended to help learn techniques and tools to cope.
