The phrase "after a density" is grammatically correct but may not be commonly used in written English without additional context.
You can use it in contexts related to measurements, scientific discussions, or descriptions involving density, such as in physics or material science.
Example: "The material's properties change significantly after a density of 2.5 grams per cubic centimeter is reached."
Alternatives: "following a density" or "subsequent to a density".
Watching my brave aunts battle, lose their hair and dignity, before sadly two of them succumbed to secondary cancers, was one of the hardest things l have experienced and why I had to honor them by opting for surgery after a density was discovered in my breast during a routine mammogram when l was 32.
