Malignant tumor is the diagnosis of the findings of a firm, non-moveable breast lump.
Step-by-step explanation:
During the physical examination of the breasts, the malignancy of a tumor is best determined by the firmness, movability, and location of the lump in the breast.
When a lump is firm and rooted, and immoveable it is considered to be malignant. Lumps that are less firm, painless and which moves upon palpation are benign lumps. Lumps filled with fluids are cysts.
Malignant lumps are commonly found along the right upper quadrant of the breasts based on common studies.
Since the lump has been located only on the current visit with the previous visit within 3 weeks before, the lump is a newly found one and even if it is proved cancer diagnostically, it would take more time to metastasize.
Hence, there are more chances for the lump to be a malignant tumor based on the physical findings but these need to be correlated with pertinent diagnostic tests .
