Anatomical Overview of the Right Chest

The right chest area is a complex region of the body, comprising various tissues, structures, and organs. Understanding its anatomy is crucial for identifying the potential causes of pain under the right breast.

Breast Tissue

The breast consists of glandular and fatty tissues, with the ratio varying among individuals. Glandular tissue includes milk-producing lobes and ducts, while fatty tissue fills the spaces between. The breast is anchored to the underlying muscles by Cooper’s ligaments, which allow for natural mobility. As women age, these ligaments may stretch, leading to breast ptosis.

Chest Wall

The chest wall provides protection for vital organs and stability for upper body movement. It consists of:

1. Skin and subcutaneous fat
2. Muscles, including the pectoralis major and serratus anterior
3. Ribs and intercostal muscles
4. Sternum, composed of the manubrium, body, and xiphoid process

The pectoralis major muscle forms the base of the breast, extending from the second to sixth rib. Intercostal spaces between the ribs contain three layers of muscles, which play a role in breathing.

Underlying Organs

Several important organs lie beneath the right chest area:

1. Right lung: Occupies the right pleural cavity
2. Heart: Although primarily on the left, a portion extends to the right side
3. Liver: Located in the upper right abdomen, just below the diaphragm
4. Gallbladder: A small organ on the right side that stores bile

Understanding this anatomical structure helps in identifying potential sources of pain under the right breast, which can originate from various tissues or organs in this region.

Respiratory System-Related Causes

Pain under the right breast can often be attributed to various respiratory system issues. These conditions affect the lungs and surrounding structures, leading to discomfort in the chest area.

Lung Infections

Lung infections, such as pneumonia, bronchitis, and bronchiolitis, can cause pain under the right breast. These infections result from viruses, bacteria, or fungi invading the respiratory system. Pneumonia, one of the most common lung infections, affects the air sacs in the lungs and can be caused by various pathogens, including Streptococcus pneumoniae and influenza viruses. Symptoms of lung infections often include chest pain, shortness of breath, coughing, and fever.

Pleural Disorders

Pleural disorders involve the tissue covering the lungs and lining the chest cavity. These conditions can lead to pain under the right breast and include:

1. Pleurisy: Inflammation of the pleura, causing sharp chest pain that worsens with breathing or coughing.
2. Pleural effusion: Buildup of excess fluid between the layers of the pleura, often described as “water on the lungs.” This condition can cause chest pain, difficulty breathing, and orthopnea (inability to breathe easily unless sitting or standing upright).
3. Pneumothorax: Accumulation of air or gas in the pleural space, which can result from injury or infection.

Asthma and COPD

Asthma and Chronic Obstructive Pulmonary Disease (COPD) are lung diseases that can cause pain under the right breast. Both conditions involve airway inflammation and obstruction, making breathing difficult. Asthma is often triggered by allergens or physical activity, while COPD is commonly caused by long-term exposure to irritants, such as tobacco smoke. Symptoms of these conditions include wheezing, coughing, chest tightness, and shortness of breath. In some cases, individuals may have Asthma-COPD Overlap (ACO), experiencing symptoms of both diseases simultaneously.

Digestive System-Related Causes

Pain under the right breast can often be attributed to various digestive system issues. These conditions affect organs such as the gallbladder, liver, and pancreas, leading to discomfort in the chest area.

Gallbladder Disease

Gallbladder disease encompasses various conditions, including inflammation, infection, and gallstones. The gallbladder, a small sac located under the liver, stores and concentrates bile. Gallstones can cause intermittent pain called biliary colic, characterized by a steady, gripping pain in the upper right abdomen that may radiate to the upper back or behind the breastbone. This pain often occurs a few hours after eating, particularly at night or early morning. Symptoms may include nausea, vomiting, and bloating.

In some cases, gallstones can lead to acute cholecystitis, an inflammation of the gallbladder. This condition causes more severe and persistent pain in the upper right abdomen, often accompanied by fever and chills. Chronic gallbladder disease may result in a scarred and stiff gallbladder, leading to complaints of gas, nausea, and abdominal discomfort after meals.

Liver Disorders

Liver diseases, such as hepatitis and cirrhosis, can cause pain felt on the right side of the chest. This discomfort often results from the inflamed liver pressing against the diaphragm. Liver pain can be challenging to diagnose, as the organ itself doesn’t contain pain-sensing nerves. Instead, pain is usually caused by inflammation or damage to surrounding tissues.

Symptoms of liver disorders may include jaundice (yellowing of the skin and eyes), dark urine, lighter stools, and general body inflammation. In some cases, liver disease can lead to ascites, a buildup of fluid in the abdomen that can cause sharp pain or discomfort when breathing.

Pancreatic Issues

Pancreatitis, an inflammation of the pancreas, can cause pain under the right breast. This condition often results from gallstones or excessive alcohol consumption. The pain associated with pancreatitis may worsen when lying down and improve when sitting up. Acute pancreatitis can present with severe, constant pain in the upper abdomen that may last for days.

In rare cases, hypertriglyceridemia-induced acute pancreatitis can occur, causing chest pain as the first symptom. This condition involves excessive triglyceride levels in the blood, leading to inflammation of the pancreas. Treatment focuses on minimizing pancreatic stimulation, providing symptom relief, and maintaining fluid and electrolyte balance.

Rare but Serious Causes

Chest Wall Tumors

Chest wall tumors are growths that form in the protective structure surrounding vital organs such as the heart, lungs, and liver. These tumors can be either cancerous or noncancerous, with about 60% being malignant. The most common type of cancerous chest wall tumor in adults is chondrosarcoma, while Ewing’s sarcoma is more prevalent in infants. Symptoms may include a palpable lump, pain, tenderness, swelling, and difficulty with movement. Treatment typically involves surgical removal of the tumor and chest wall reconstruction, with additional radiation therapy or chemotherapy for cancerous growths.

Thoracic Outlet Syndrome

Thoracic outlet syndrome (TOS) occurs when nerves or blood vessels in the lower neck and upper chest are compressed. This compression can lead to pain, abnormal sensations, and other symptoms in the upper body. TOS has three main types: neurogenic, venous, and arterial. Neurogenic TOS often responds well to physical therapy, while venous and arterial TOS may require surgical intervention. Without treatment, TOS can lead to serious complications such as blood clots, chronic arm swelling, and permanent nerve damage.

Referred Pain from Other Conditions

Pain under the right breast can sometimes be referred from other conditions. Gallbladder issues, such as gallstones, can cause pain in the upper right abdomen that may radiate to the chest area. Pleurisy, an inflammation of the membranes surrounding the lungs, can result in sharp chest pain that worsens with breathing or coughing. Additionally, pneumonia can cause pain in the chest area, along with other symptoms like fever, coughing, and difficulty breathing.
