Breastfeeding with a lump on the breast

When i was preggy I found out I had a lump on my left breast. Eventually I went for the biopsy test as was told to check if is cancerous thankfully it turns out it’s not cancerous but was told to remove it after I’ve gave birth. In May I’ve gave birth and will only consult the doctor August. My question is , is it safe for breastfeeding. It just occurred my mind and I’ve been bf-ing my LO for a month. Feeling kind of worried.):
