# non-SOP condition
Clinical onset will generally be when a breast lump (subsequently confirmed to be a breast cancer) is first found or when a screening mammogram first shows evidence of the condition.
The only SOP worsening factor is for inability to obtain appropriate clinical management. The disease has a very variable course and prognosis. It is particularly amenable to treatment if found early. A delay in appropriate treatment could result in worsening of the condition. Establishing whether worsening beyond the normal course of the disease has occurred will generally require expert medical opinion.
