Thanks for the query.
Better to consult gynecologist once, go for physical examination.
And you may need:
-Sonomammography and FNAC to detect the actual nature of the lump in the breast.
to diagnose the possible causes for irregular periods
-Estimation of prolactin
levels and thyroid profile.
With this workup the possible cause for your problem can be identified and treated.
