Male breast cancer is a type of cancer that grows in the breast tissue in your chest. Although men and people assigned male at birth (AMAB) don’t have breasts that produce milk, they have fatty tissue, ducts and breast cells that can become cancerous. Cancer develops when cells in these tissues grow uncontrollably, forming a tumor. Male breast cancer is extremely rare compared to breast …
Inflammatory breast cancer (IBC) is a rare type of cancer that spreads quickly. Unlike most breast cancers, IBC doesn’t usually cause lumps in breast tissue. Instead, it appears as a rash, creating skin texture on the affected breast similar to an orange peel. IBC causes pain, redness, swelling and dimpling on the affected breast. IBC results when cancer cells block lymph vessels — …
Pediatric brain tumors are growths of cells that start in or near the brain in children. The growths, called tumors, can grow to press on nearby parts of the brain. This can cause symptoms, such as headaches and nausea. Many types of pediatric brain tumors exist. Some grow quickly, and some grow slowly. Some are cancerous, and some aren’t cancerous. …
A brain tumor is an abnormal growth or mass of cells in or around your brain. Together, spinal tumors and brain tumors are called central nervous system (CNS) tumors. Brain tumors can be malignant (cancerous) or benign (noncancerous). Some tumors grow quickly, while others are slow growing. Only about one-third of brain tumors are cancerous. But whether they’re cancerous or not, brain tumors can impact …
Brain metastases are a type of metastatic cancer. They occur when a malignant tumor in one part of your body spreads to your brain. The original tumor is called the primary tumor/cancer. Most brain metastases spread from primary cancers in your lungs, breasts or skin (specifically melanoma). Once the cancer cells reach your brain, they form one or more new tumors. The impact the tumors have on your body depends …
A brain arteriovenous malformation (AVM) is a tangle of blood vessels that creates irregular connections between arteries and veins in the brain. Arteries take oxygen-rich blood from the heart to the brain. Veins carry oxygen-depleted blood back to the lungs and heart. A brain AVM disrupts this vital process. An arteriovenous malformation can develop anywhere in the body, but common …
Sick sinus syndrome is the name for heart rhythm problems that happen because your sinoatrial node (or sinus node) isn’t working right. The sinus node acts like a pacemaker that kicks off each heartbeat. Also called the SA node, the sinus node is like a drummer starting and keeping the beat for others to follow. Musicians listen to the drummer so they …
Bradycardia is a condition where your heart beats fewer than 60 times per minute, which is unusually slow. This condition may be dangerous if it keeps your heart from pumping enough blood to meet your body’s needs. However, bradycardia can also happen without causing any harmful effects, especially in very physically active people. How do I know if I have …
The brachial plexus is a network of intertwined nerves that control movement and sensation in your arm and hand. A brachial plexus injury involves sudden damage to these nerves, which may cause pain, weakness, loss of feeling, or loss of movement in your shoulder, arm and/or hand. The brachial plexus begins at your neck and crosses your upper chest to …
Intestinal obstruction is a blockage that keeps food or liquid from passing through your small intestine or large intestine (colon). Causes of intestinal obstruction may include fibrous bands of tissue (adhesions) in the abdomen that form after surgery; hernias; colon cancer; certain medications; or strictures from an inflamed intestine caused by certain conditions, such as Crohn’s disease or diverticulitis. Without …
