Skin cancer in horses: Skin cancer, or neoplasia, is the most common type of cancer diagnosed in horses, accounting for 45 to 80% of all cancers diagnosed.  Sarcoids are the most common type of skin neoplasm and are the most common type of cancer overall in horses.  Squamous-cell carcinoma is the second-most prevalent skin cancer, followed by melanoma.  Squamous-cell carcinoma and melanoma usually occur in horses greater than 9-years-old, while sarcoids commonly affect horses 3 to 6 years old.  Surgical biopsy is the method of choice for diagnosis of most equine skin cancers, but is contraindicated for cases of sarcoids.  Prognosis and treatment effectiveness varies based on type of cancer, degree of local tissue destruction, evidence of spread to other organs (metastasis) and location of the tumor.  Not all cancers metastasize and some can be cured or mitigated by surgical removal of the cancerous tissue or through use of chemotherapeutic drugs.

The album was conceived to introduce American audiences to happy hardcore, and contains sixteen of the genre's anthems which carry many of happy hardcore's defining characteristics, such as fast tempo, frantic breakbeats, major key tonality, off-kilter, quirky keyboard effects and "semi-melodies."

Tacky (song): "Tacky" is a song by American musician "Weird Al" Yankovic from his fourteenth studio album, "Mandatory Fun" (2014).

Yankovic recorded the song as one of the last on "Mandatory Fun", and received Williams' approval directly, through email.  He remarked he was "honored" to have his work spoofed by Yankovic.

Uterine cancer: Uterine cancer or womb cancer is any type of cancer that emerges from the tissue of the uterus.  It can refer to several types of cancer, with cervical cancer (arising from the lower portion of the uterus) being the most common type worldwide and the second most common cancer in women in developing countries.  Endometrial cancer (or cancer of the inner lining of the uterus) is the second most common type, and fourth most common cancer in women from developed countries.  Risk factors depend on specific type, but obesity, older age, and human papillomavirus infection add the greatest risk of developing uterine cancer.  Early on, there may be no symptoms, but irregular vaginal bleeding, pelvic pain or fullness may develop.  If caught early, most types of uterine cancer can be cured using surgical or medical methods.  When the cancer has extended beyond the uterine tissue, more advanced treatments including combinations of chemotherapy, radiation therapy, or surgery may be required.
