These may reflect endogenous or environmental hormones.Higher rates of testicular cancer in Western nations have been linked to the use of cannabis. Mechanisms
Most testicular germ cell tumors have too many chromosomes, and most often they are triploid to tetraploid. An isochromosome 12p (the short arm of chromosome 12 on both sides of the same centromere) is present in about 80% of the testicular cancers, and also the other cancers usually have extra material from this chromosome arm through other mechanisms of genomic amplification. Diagnosis
The main way testicular cancer is diagnosed is via a lump or mass inside a testis. More generally, if a young adult or adolescent has a single enlarged testicle, which may or may not be painful, this should give doctors reason to suspect testicular cancer. Other conditions may also have symptoms similar to testicular cancer:
Epididymitis or epididymoorchitis
Hematocele
Varicocele
Orchitis
Prostate infections or inflammations (prostatitis), bladder infections or inflammations (cystitis), or kidney (renal) infections (nephritis) or inflammations which have spread to and caused swelling in the vessels of the testicles or scrotum
Testicular torsion or a hernia
Infection, inflammation, retro-peritonitis, or other conditions of the lymph nodes or vessels near the scrotum, testicles, pubis, anorectal area, and groin
Benign tumors or lesions of the testicles
Metastasis to the testicles from another, primary tumor site(s)The nature of any palpated lump in the scrotum is often evaluated by scrotal ultrasound, which can determine exact location, size, and some characteristics of the lump, such as cystic vs solid, uniform vs heterogeneous, sharply circumscribed or poorly defined.
Periodontosis is an obsolete term that was used to describe what was once thought to be certain type of unique and distinguishable chronic periodontal disease that manifested as degenerative bony changes without concomitant inflammation. Although utilized for more than 50 years, the term has since been dropped in favor of a more contemporary disease classification for periodontal disease. Described by Gottlieb as a "diffuse atrophy of the alveolar bone," the term periodontosis was later applied and it gained acceptance as a disease entity,  being defined as:

"a degenerative, noninflammatory destruction of the periodontium, originating in one or more of the periodontal structures and characterized by migrating and loosening of the teeth in the presence or absence of secondary epithelial proliferation and pocket formation or secondary gingival disease. "Noted as a rare disease, periodontosis was said to have been seen primarily in young patients. And despite being defined as being a "noninflammatory destruction of the periodontium," almost all cases did exhibit varying degrees of gingival inflammation. References
