Some issues Dr. Mark L. Koransky, MD, FACS 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.

Gallbladder Removal Surgery (Cholecystectomy)

The gallbladder is a small, pear-shaped organ on the right side of the upper abdomen, underneath the liver. Its purpose is to store bile, which is used to digest fat. Occasionally, the gallbladder can develop mineral stones, called gallstones. If they are large enough, gallstones can block the ducts in the gallbladder and cause swelling and infection. Gallstones can be treated with lifestyle changes and medication, but sometimes this is not enough. In these cases, it is best to remove the gallbladder before it can cause more serious problems. The surgical removal of the gallbladder is called a cholecystectomy.

Today, most gallbladder surgeries are done laparoscopically. Four tiny incisions are made in the abdomen, and small tools are inserted through these tiny incisions to perform the surgery. Because the incisions are much smaller, recovery time is much faster with this type of surgery. Patients are usually discharged from the hospital the same day. Sometimes, open surgery is used to remove a gallbladder. In this type of surgery, a cut about six inches long is made in the upper right abdomen. After the gallbladder is removed, it is sutured or stapled closed. With open surgery, patients usually stay in the hospital for two to three days to recover before they are discharged.

Gallbladder removal, like any surgery, carries some risks, such as bleeding, infection, or the development of blood clots. Doctors will tell patients how to minimize their risk for complications. After surgery, patients are advised to avoid strenuous activity for several days. They should not soak in a bath until their sutures or staples have been removed. Patients should wash hands before touching the area around the incision. It will take a couple of days until patients feel like themselves again and a few weeks until their scar has healed and faded.

Mastectomy (Breast Removal Surgery)

Mastectomy is the surgical removal of all or part of the breasts, most frequently associated with breast cancer treatment (for both male and female breast cancer patients). Breast cancer patients who receive a mastectomy typically have undergone other treatments, such as chemotherapy, radiation, and less invasive breast-conserving surgery (lumpectomy). If these treatments are unsuccessful, oncologists may eventually prescribe a mastectomy. Other conditions that may prompt a mastectomy include:

Two or more cancerous regions in the same breast
Inability to receive chemotherapy or radiation therapy
High likelihood of recurring breast cancer
Large tumor that is bigger than two inches across
Pregnancy that prohibits radiation therapy
Preexisting conditions like lupus or scleroderma

Notably, some patients may elect to undergo mastectomy without a breast cancer diagnosis. Preventative (prophylactic) mastectomy is performed on those with a high risk of breast cancer, such as having a family history of the disease or carrying the breast cancer BRCA1 or BRCA2 gene. Preventative mastectomy substantially reduces one's chances of developing breast cancer in the future, but it cannot wholly prevent it.

Surgical oncologists perform several types of mastectomies, depending upon the severity of the breast cancer (including factors such as its location and spread), as well as the patients' own aesthetic and personal choices. The six main types of mastectomy include:

Total mastectomy, where the surgical oncologist removes an entire breast, including parts like the pectoral chest muscle, skin, and nipple.
Radical mastectomy, where the surgical oncologist removes the entire breast, underarm lymph nodes, pectoral chest muscles, and outer skin and nipple. One of the most invasive forms of mastectomy, radical mastectomy is infrequently performed.
Modified radical mastectomy, where the surgical oncologist completes a total mastectomy and also removes the underarm lymph nodes. This procedure is slightly less invasive than radical mastectomy.
Skin-sparing mastectomy, where the surgical oncologist removes cancerous breast tissue and nipple, but leaves most of breast skin. This method is used in conjunction with breast reconstruction, as implants can be added below the skin. Skin-sparing mastectomy often requires a treatment team with a surgical oncologist and a plastic surgeon experienced in breast procedures.
Nipple-sparing mastectomy, where the surgical oncologist removes cancerous breast tissue and leaves the nipple and most of the breast skin. This method is only available to patients in the early stages of breast cancer. Similar to skin-sparing mastectomy, this procedure is frequently performed with breast reconstruction.

Any of these procedures can be done on both breasts, in which case the procedure would be known as a double mastectomy. For example, a surgical oncologist might perform a total or nipple-sparing mastectomy on both breasts. Double mastectomies are often used as a preventive surgery for those who are at risk of developing breast cancer later on in life.

Patients have one or two days of hospital stay before returning home from their mastectomy procedures. Full recovery can take several months, but some patients find they are able to resume normal activity within one month of their mastectomy. Patients are advised to limit arm and chest movements whenever possible.

After surgery, patients must also adjust to changes in their appearance. While some patients choose to receive breast reconstruction, other patients may decide to wear prosthetic breasts or will simply embrace their new chest.

Mastectomies permit patients to conquer cancer and lead healthy, thriving lives as breast cancer survivors.
