Breast lumps are relatively common in young women. With breast lumps, the main worry for most patients would be whether these lumps are malignant or not.
My first advice would definitely be to see a doctor to consult regarding your breast lump.
Breast lumps can usually be investigated via a breast ultrasound for younger women, and if any suspicious features are found, a biopsy or review by a breast specialist may then be recommended.
Ultrasound costs will vary depending on the clinic you visit, whether it is a private or government clinic.
