Some issues Dr. Alexander S. Mark, MD can help you with:

Breast Biopsy

Breast biopsy is a procedure where a small sample of tissue is collected from the breast for testing. A physician may prescribe a breast biopsy for a variety of reasons, but they are most frequently prescribed for a lump found in the breast. Biopsy samples extracted are examined by pathologists in a laboratory setting and are tested to determine if they are cancerous or benign, or indicative of some other condition. Depending on the lab results, physicians may prescribe additional treatment. Other circumstances which may prompt a breast biopsy include:

Mammograms that detect other unusual features in the chest, such as a cyst or calcium deposit
Breast scans or ultrasounds that display abnormalities
Nipple changes, such as scaling, crusting, or bloody discharge

Breast biopsies are collected through several different procedures and the specific type of biopsy that a patient receives depends on the size, location, and features of a breast lump or irregularity. The three main methods of collecting a breast biopsy include:

Fine needle aspiration (FNA biopsy), where a thin needle is directed into a breast lump or abnormality, extracting a small sample of tissue or liquid
Core needle biopsy (CNB biopsy), where a hollow needle is directed into a breast lump or abnormality, extracting cylinders of tissue called "cores"
Open (surgical) biopsy, where a breast lump is removed through an incision in the breast

Fine needle aspiration (FNA) and core needle biopsy (CNB) are sometimes image-guided, where a mammogram, ultrasound, or MRI helps direct the physician performing the needle extraction.

Fine needle aspiration, the most common biopsy method, generally requires few patient preparations. It is recommended patients avoid using lotion, deodorant, and perfume prior to their biopsy procedure. FNA biopsy is performed with local anesthesia (topical numbing cream) and typically has a quick recovery, but patients may experience soreness for a few days. Core needle biopsy extracts slightly more tissue than an FNA biopsy.

Open (surgical) biopsy is more invasive and requires general anesthesia, where patients are put to sleep during the procedure. Patients must fast prior to the surgery. After the biopsy is performed, patients are monitored in a recovery room for a time before being discharged, when they will need someone else to provide transportation.

Although some may consider breast biopsy to be a simple procedure, it can catch critical issues - particularly breast cancer - that impact wellness. If a breast biopsy reveals an underlying condition like life-threatening cancer, patients can receive the diagnosis and medical treatment that is necessary for their long-term health.

Kidney Stones

Kidney stones are hard deposits that form in the kidneys, made up of minerals that are normally present in urine. They can vary in size, from as small as a grain of sand to as large as a nickel, occasionally even larger. Sometimes they lodge in the kidney, and sometimes they break free and make their way out through the urinary tract, which can be extremely painful.

Kidney stones can be smooth or jagged and are yellow to brown in color. They are mostly comprised of the minerals calcium, oxalate, and phosphorus. Examining the stones to see what they are made of can show what caused the stone to be formed in the first place. For example, a stone made of mostly calcium, which is the most common type, can happen any time the urine becomes too concentrated due to dehydration or a blockage in the kidney. A uric acid stone forms when acid levels in the urine get too high, usually due to excessive consumption of animal protein such as meat and fish. A struvite stone is a sign of certain infections, and a cystine stone can be due to a genetic disorder that raises the risk of kidney stones.

The most common symptom of kidney stones is pain, either in the back or lower abdomen, or severe pain when urinating. There may also be blood in the urine. Treatment for kidney stones depends on how large the stone is. Very small stones can pass out of the body on their own, and they do not require treatment other than drinking adequate water and taking pain killers. Larger stones need to be broken apart and removed. The main treatment options are:

Shock wave lithotripsy, which uses sound wave vibrations to break apart the stone
Percutaneous nephrolithotomy, or the use of a very tiny tool (like a wire inserted through the back) to break apart and remove the stone
Ureteroscopy, a thin tube inserted through the urethra and bladder to the stone, where tiny tools can grasp the stone and remove

People who have had one kidney stone are at risk of developing another. To reduce this risk, patients are given instructions specific to the type of stone they developed. Generally the instructions will include drinking more water to dilute the urine, but it may also involve lowering sodium intake or eating less meat.

Lung Issues

Every cell in the body requires oxygen to function and produces carbon dioxide as a waste product. In order to keep the body's tissues constantly supplied with fresh oxygen and to keep waste from building up, the lungs pump air in and out, even while sleeping or unaware. Unfortunately, diseases and disorders affecting the lungs are some of the most common medical problems afflicting people around the world. Some of the most common lung problems include asthma, COPD, pneumonia, and lung cancer.

Asthma is a chronic disease where swollen, inflamed airways make it hard to breathe. It is often brought on by specific triggers. While asthma is a common condition, affecting millions of people, it can also be serious and even fatal in severe cases. Treatment involves avoiding triggers and using inhaled corticosteroid medications.

COPD, or Chronic Obstructive Pulmonary Disease, is the name given to two illnesses that both cause difficulty breathing: emphysema and chronic bronchitis. In emphysema, the air sacs of the lungs become damaged, while with bronchitis they become clogged with mucus. COPD is the fourth leading cause of death in the United States. It is almost always caused by breathing irritants into the lungs, such as smoking or heavy pollution.

Pneumonia is a lung infection that can be caused by bacteria, a virus, or fungi. Most healthy people recover from pneumonia in a week or two, but for some people pneumonia can be fatal. There are treatments available for pneumonia, but the best treatment is to prevent getting sick in the first place. People who are at risk should make sure they get a flu shot every year. There is also a vaccine available for the type of bacteria that causes pneumonia.

Lung cancer occurs when abnormal cells inside the lung grow into a tumor, destroying healthy tissue. Because it is so difficult to detect lung cancer in early stages when it has few symptoms, it is the deadliest form of cancer, responsible for the most cancer deaths both in the U.S. and worldwide. Most lung cancer is caused by exposure to tobacco smoke, but between 10-15% of cases are not linked to smoking.

Some problems with the lungs are minor and are not cause for concern. However if symptoms have lasted for a month or more, even if they are minor, it is worth checking with a healthcare professional. A cough, shortness of breath, or excess mucus production that lingers for weeks are all worth getting looked at.
