  You might think that it is a heart attack but most of the times, it could easily be a breast infection or simple inflammation. One should visit the gynecologist if something like that persists. The doctor might prescribe you with some drugs.
• Hormonal changes
  Sometimes the breasts become soft and sensitive towards touch due to hormonal changes or during menstruation cycles. Even taking oral contraceptives can cause the same. Although this pain usually occurs in both the breasts, however, many times, it is felt in only one of the breasts.
• Left-sided breast cancer
  It has been noted by many medical studies that in most cases, cancer is painless up to a certain stage. However, some kinds of breast cancers begin with pain, redness and more symptoms like these. Sometimes it might be hard to find a lump but one should not rule out the possibility of the same.

  Sometimes the chest muscles under the breast might go into a spasm. This pain may last for a few seconds or even for days. This pain may occur on just one side. Even if you have had a muscle pull, the same might occur.

• Pneumonia
  Left breast pain in women can also be caused by pneumonia since the lungs are in the chest area, which lies under the breasts.
• Cartilage
  Sometimes, it might feel like a cancer lump but it could be a cartilage that has been hurting in the breastbone. This can cause pain in either of the breasts. This condition is known as costochondritis and occurs between the rib and breastbone junction.
• Esophagus
  Since the esophagus originates from below the left breast, it is possible that a problem in the esophagus is what is causing the pain. This could either feel like a burning pain or even give an acidic taste in your mouth. Some other digestive issues might also cause the same kind of pain.
