However, the American Cancer Society suggests that some men should examine their testicles monthly, especially if they have a family history of cancer, and the American Urological Association recommends monthly testicular self-examinations for all young men.Symptoms may also include one or more of the following:

a lump in one testis which may or may not be painful
sharp pain or a dull ache in the lower abdomen or scrotum
a feeling often described as "heaviness" in the scrotum
firmness of the testicle
breast enlargement (gynecomastia) from hormonal effects of β-hCG
low back pain (lumbago) due to the cancer spreading to the lymph nodes along the backIt is not very common for testicular cancer to spread to other organs, apart from the lungs. If it has, however, the following symptoms may be present:

shortness of breath (dyspnea), cough or coughing up blood (hemoptysis) from metastatic spread to the lungs
a lump in the neck due to metastases to the lymph nodesTesticular cancer, cryptorchidism, hypospadias, and poor semen quality make up the syndrome known as testicular dysgenesis syndrome. Causes
A major risk factor for the development of testis cancer is cryptorchidism (undescended testicles). It is generally believed that the presence of a tumor contributes to cryptorchidism;  when cryptorchidism occurs in conjunction with a tumor then the tumor tends to be large. Other risk factors include inguinal hernias, Klinefelter syndrome, and mumps orchitis. Physical activity is associated with decreased risk and sedentary lifestyle is associated with increased risk. Early onset of male characteristics is associated with increased risk.
Potassium bicarbonate (IUPAC name: potassium hydrogencarbonate, also known as potassium acid carbonate) is the inorganic compound with the chemical formula KHCO3. It is a white solid. Production and reactivity
It is manufactured by treating an aqueous solution of potassium carbonate with carbon dioxide:
K2CO3 + CO2 + H2O → 2 KHCO3Decomposition of the bicarbonate occurs between 100 and 120 °C (212 and 248 °F):

2 KHCO3 → K2CO3 + CO2 + H2OThis reaction is employed to prepare high purity potassium carbonate. Uses
Food and drink
This compound is a source of carbon dioxide for leavening in baking. It can substitute for baking soda (sodium bicarbonate) for those with a low-sodium diet, and it is an ingredient in low-sodium baking powders.As an inexpensive, nontoxic base, it is widely used in diverse application to regulate pH or as a reagent. Examples include as buffering agent in medications, an additive in winemaking. Potassium bicarbonate is often found added to club soda to improve taste, and to soften the effect of effervescence. Fire extinguishers
Potassium bicarbonate is used as a fire suppression agent ("BC dry chemical") in some dry chemical fire extinguishers, as the principal component of the Purple-K dry chemical, and in some applications of condensed aerosol fire suppression. It is the only dry chemical fire suppression agent recognized by the U.S. National Fire Protection Association for firefighting at airport crash rescue sites. It is about twice as effective in fire suppression as sodium bicarbonate.
