Sore Breasts

Breast soreness and pain (mastalgia in medical terms) is one of the most common symptoms during pregnancy. The pain usually occurs around 4 – 7 weeks and lasts throughout the 1st trimester.

Mastalgia varies from woman to woman. The pain can range from mild soreness to a stabbing pain. Some may feel tenderness while some may feel that their breasts are heavier than usual. It can occur on a single breast or both, the full breast or a localized area only.

Apart from that, the lady lumps / chesticles (two milk – secreting and glandular organs on a woman’s chest) will continue to grow exponentially in size throughout pregnancy. This is because the milk ducts are culminating the supply of colostrum – precursor to breastmilk and the newborn’s first food right after childbirth [which will begin to leak around week 38].

On the bright side, the breasts may continue to grow but the soreness and pain will subside after the 1st trimester. The breasts will also [almost] return to their pre – pregnancy size a few months after birth.


Types of breast pain

Cyclical breast pain

Cyclical is the most common types of breast pain which occurs during a monthly cycle. It is characterized by soreness and heaviness caused by the expansion of milk ducts. The pain affects both breasts and radiates through the armpits and the arms.

Pregnancy week by week

Cyclical breast pain occurs in a regular schedule, it sets right before the period begins and during the 1st day of the menstrual flow. The pain usually becomes more severe before the period ends and permanently disappears when menopause sets in.

This type of pain is associated with fibrocystic breast tissues which refer to the lumpy and even breast tissues caused by the fluid – filled cysts.

Non – cyclical breast pain

Non – cyclical is a type of breast pain which does not follow any scheduled pattern. It is characterized by a stabbing and burning pain which only occurs in one breast of women ages 30 – 50. Furthermore, non – cyclical breast pain is caused by the following:

  • Fibroadenoma (fibroadenomas in plural form) – are the non – cancerous tumors in a gland. This usually occurs in women ages 13 up to their early 20s and are common in the African – American race
  • Benign breast cyst
  • Breast injury
  • Pain may stem from surrounding muscles and tissues

Causes of breast soreness and pain

Moreover, the types of pregnancy below can also contribute to Mastalgia:

  • Teenage pregnancy
  • Ectopic pregnancy

Pre – menstrual syndrome

Pre – menstrual syndrome (PMS) is the most common cause of breast soreness and pain. It is the body’s way of responding to estrogen fluxes which results to swelling and tenderness.


Atypical prolactin levels is a single breast hurts more than the other.


Puberty causes breast pain on both girls and boys.

Fibrocystic breast disease

Fibrocystic breast disease causes the breasts to look and feel lumpy which results to breast soreness and pain. In some cases, sore lumps are caused by breast cancer. On the bright side, having fibrocystic breasts is not a definite sign of developing cancer.

Intraductal papilloma

Intraductal papilloma is the non – cancerous breast tumors in the milk ducts.


Perimenopause refers to the stage of a woman’s (women ages 45 – 55) life shortly before menopause sets in. Breast pain indicates either the reproductive system is proceeding for the next menstrual cycle or the reproductive organs are nearing to stop its function.

Common causes

Fat build – up

Most expectant mothers gain weight during pregnancy, and fat build – up in the breasts is one of the contributing factors.

Increased blood flow

Blood flow increases in the breasts during pregnancy. This is to prepare the milk ducts for future breastfeeding sessions.

Pectoral exercises

Pectoral exercises (also called as pecs workout) are activities that engage the pectorals, can strain the chest muscles such as the pectoralis major – muscle tissues underneath the breasts.

Pain from these types of workouts is always confused with breast soreness. But this type of pain is simply caused by the straining of pectorals.

Carrying heavy objects

Carrying heavy objects (which is correlated to pectoral exercises) also strains the pectoral muscles.

Wearing the wrong bra

Choosing and wearing the wrong bra can cause some serious consequences to the breasts. To know if she is wearing the wrong one below are following indications:

  • Cup size are too small

  • Providing inadequate support which is unable to control breast movements (bouncing up and down) which pulls the tissues

Three – cup – a – day habit

Did you know that too much coffee consummation can cause the breasts to sore? It is believed that too much coffee consummation have an effect on breast sensitivity. In fact, some women find that cutting back the caffeine consummation has diminished the soreness and pain.

In line with this, studies show that having a three – cup – a – day habit can cause soreness and pain especially to women with fibrocystic breasts [who are said to be more vulnerable to chesticles pain].
