Understanding Breast Cancer: Symptoms and Diagnosis

Breast cancer is a type of cancer that affects the breast tissue. It is the second most common type of cancer in women worldwide, with an estimated 2.3 million new cases diagnosed in 2020 alone. While breast cancer can also affect men, it is much less common in males. Understanding breast cancer, its symptoms, diagnosis, and treatment options is crucial in early detection and improving outcomes for those diagnosed with the disease. In this blog post, we will discuss these important topics.

Symptoms of Breast Cancer

Breast cancer can present itself in many different ways. Some common symptoms include:

A lump or mass in the breast or underarm area

Pain or tenderness in the breast or nipple

Changes in the size or shape of the breast

Skin changes, such as redness or thickening

Nipple discharge that is not breast milk

Changes in the appearance of the nipple, such as becoming inverted or pointing in a different direction

It is important to note that not all cases of breast cancer present with symptoms, which is why regular screening is recommended for early detection.

Diagnosis of Breast Cancer

If you have symptoms of breast cancer, your doctor may recommend further testing. This may include:

Mammogram: A mammogram is an X-ray of the breast tissue. It is the most common screening test for breast cancer and can often detect the disease before symptoms are present.

Ultrasound: An ultrasound uses sound waves to create an image of the breast tissue. It can be helpful in determining whether a lump is solid or fluid-filled.

Biopsy: A biopsy involves removing a small piece of breast tissue for examination under a microscope. This is the only way to definitively diagnose breast cancer.

Surgery

Surgery is often the first line of treatment for eye cancer. It involves removing the cancerous tissue from the eye. The type of surgery depends on the location and size of the tumor. Some of the common surgical procedures include:

Enucleation: This involves removing the entire eye, including the tumor.

Evisceration: This involves removing the contents of the eye, but leaving the sclera intact.

Orbital exenteration: This involves removing the entire eye and surrounding tissues, including the eyelids and the bone around the eye.

Dr. Vijay Karan Reddy, our eye cancer specialist in Hyderabad, has extensive experience in performing these surgeries and ensuring the best possible outcome for our patients.

Radiation Therapy

Radiation therapy involves using high-energy radiation to kill cancer cells. It can be used alone or in combination with surgery. There are two types of radiation therapy:

External beam radiation therapy: This involves using a machine outside the body to deliver radiation to the tumor.

Brachytherapy: This involves placing radioactive seeds inside the eye near the tumor.

Radiation therapy can cause some side effects such as dryness and irritation of the eye, but these are usually temporary and can be managed with medication.

Chemotherapy

Chemotherapy involves using drugs to kill cancer cells. It can be given orally, injected into a vein, or placed directly into the eye. Chemotherapy is often used in combination with other treatments such as surgery and radiation therapy.

What are the different types of BMT?

Bone marrow transplant (BMT) is a complex medical procedure that involves replacing damaged or diseased bone marrow with healthy bone marrow stem cells. There are several types of BMT that are used depending on the patient's medical condition and the purpose of the transplant. In this blog post, we will discuss the different types of BMT and how they work.

Autologous BMT: In this type of BMT, the patient's own stem cells are used for the transplant. These stem cells are harvested from the patient's bone marrow or blood and then stored. After undergoing high-dose chemotherapy or radiation therapy, the stored stem cells are infused back into the patient's bloodstream to help rebuild the damaged bone marrow.

Allogeneic BMT: This type of BMT involves using stem cells from a donor, usually a close family member or an unrelated donor whose tissue type matches the patient's. Before the transplant, the patient undergoes chemotherapy or radiation therapy to eliminate any cancer cells and to suppress the immune system to prevent rejection of the donor cells. The donor stem cells are then infused into the patient's bloodstream to replace the damaged bone marrow.

Syngeneic BMT: This type of BMT is similar to allogeneic BMT, but the donor is an identical twin of the patient. Because identical twins share the same genetic makeup, there is no risk of rejection of the donor cells.

In addition to these types of BMT, there are also different methods of delivering radiation therapy to the patient as part of the transplant process. One such method is Tomotherapy, a type of radiation therapy that delivers targeted radiation to the affected area while minimizing exposure to healthy tissue. In Hyderabad, there are Bone Marrow Transplant Specialist who utilize Tomotherapy as a part of the BMT procedure.

Another technique that is used is Stereotactic Radiation Therapy, which is a highly precise form of radiation therapy that targets small tumors or lesions. This can be used in conjunction with BMT to target specific areas of the body that are affected by cancer.

In conclusion, Bone Marrow Transplant is a complex medical procedure that requires careful consideration of the patient's medical condition and the purpose of the transplant. There are different types of BMT, each with its own unique benefits and risks. With the help of Bone Marrow Transplant Specialists and advanced technologies like Tomotherapy and Stereotactic Radiation Therapy, patients in Hyderabad can receive the best possible care and treatment for their medical condition.

How to detect throat cancer early and what treatment options are available

The diagnosis of throat cancer is an alarming and frightening ordeal for those affected by it. Early detection and treatment of the disease are essential to increase the chances of a successful outcome. With advances in medical technology, the prognosis for throat cancer has improved significantly in recent years, making early detection and treatment more important than ever. In this article, we will explore the options available for the early detection and treatment of throat cancer and any associated risks or side effects.

Symptoms

Some common signs and symptoms of throat cancer include a persistent sore throat, difficulty swallowing, hoarseness, and a lump in the neck. If you have any of these symptoms, you must see a doctor as soon as possible.

Diagnosis

Dr. Vijay Karan, the top oncologist, might advise the following in order to identify throat cancer:

Examining your neck more closely using a scope. During a procedure known as an endoscopy, Dr. Vijay Karan may use a specialized lighted scope (endoscope) to have a close look at your throat. He examines the images from a camera at the end of the endoscope on a video screen to look for any indications of abnormalities in your throat.

You can have a laryngoscope (an additional scope) placed into your voice box. It aids your doctor in inspecting your vocal cords using a magnifying lens.

Removing a sample of tissue for analysis. During an endoscopy or laryngoscopy, if abnormalities are discovered, he may insert surgical instruments through the scope to get a tissue sample (biopsy). The sample is delivered to a lab for analysis.

Dr. Vijay Karan may use imaging tests like computerized tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET) to ascertain the amount of your cancer's spread past the neck or voice box's surface.

Facts and myths about breast cancer

Breast cancer is the most common cancer in women, with every 1 in 8 being diagnosed. As much as there is increasing awareness about its prevention and especially early detection, it’s important to bust the myths of breast cancer as well to make sure you don’t “miss the trick” and end up delaying the diagnosis. This October being Breast Cancer Awareness Month, let’s busy the myths about breast cancer!

1. Only older people can develop breast cancer.

Even though the likelihood that a breast lump is cancerous is higher in elderly women, it is never zero. Breast cancer is known to strike people of all ages, so even a young girl should see a doctor and get checked out if she notices a sudden change in how her breast feels or looks.

2. Breast cancer cannot develop while a woman is pregnant or breastfeeding.

When pregnant or breastfeeding, most women ignore subtle breast symptoms because they think they are “normal” changes. This frequently turns out to be dangerous and may delay diagnosis. Although early pregnancy and breastfeeding lower a woman’s lifetime risk, cancer can manifest during these times.

3. Breast cancer may develop when tight, underwired, or black bras are worn.

One of the most prevalent pieces of false information about breast cancer frequently spread among women is this one. Your underwear selection is crucial for your comfort but does not affect your likelihood of developing breast cancer.

4. Deodorants cause breast cancer.

There is no conclusive scientific evidence connecting the use of deodorants and antiperspirants with an elevated risk of developing breast cancer, despite claims that underarm deodorants containing aluminum and parabens may be carcinogenic.

Why Stomach cancers are increasing in south India?

Stomach cancer is a serious health issue in many parts of the world, including South India. The reasons behind the increase in stomach cancer in South India are not entirely clear, but several factors may be contributing to this trend.

One of the factors is the high consumption of salted and pickled foods, which are common in South India. These foods contain high levels of nitrates and nitrites, which can increase the risk of stomach cancer. In addition, a high intake of spicy foods and a lack of fruits and vegetables in the diet may also be contributing factors.

Another factor is the high prevalence of Helicobacter pylori (H. pylori) infection in the population. H. pylori is a type of bacteria that can cause stomach inflammation and increase the risk of developing stomach cancer. In South India, H. pylori infection is common due to poor sanitation and hygiene practices.

Additionally, lifestyle factors such as smoking and alcohol consumption have been associated with an increased risk of stomach cancer. Some studies have also suggested that genetic factors may play a role in the development of stomach cancer.

To reduce the risk of developing stomach cancer, individuals in South India can take several steps, including reducing their consumption of salted and pickled foods, increasing their intake of fruits and vegetables, practicing good hygiene, and quitting smoking and reducing alcohol consumption. Additionally, screening and early detection of H. pylori infection can also help reduce the risk of developing stomach cancer.

Immunotherapy: A new cancer treatment

Immunotherapy is a type of cancer treatment that works by using the body's own immune system to fight cancer. Unlike chemotherapy and radiation therapy, which directly target cancer cells, immunotherapy works by helping the immune system recognize and attack cancer cells.

There are several types of immunotherapy, including checkpoint inhibitors, CAR-T cell therapy, and cancer vaccines. Checkpoint inhibitors work by blocking proteins on the surface of immune cells that inhibit their ability to recognize and attack cancer cells. CAR-T cell therapy involves modifying a patient's own T cells to recognize and attack cancer cells. Cancer vaccines work by stimulating the immune system to recognize and attack cancer cells.

Immunotherapy has shown promise in treating a variety of cancers, including melanoma, lung cancer, bladder cancer, and certain types of leukemia and lymphoma. It has also been used in combination with other cancer treatments, such as chemotherapy and radiation therapy, to improve outcomes for some patients.

However, not all patients respond to immunotherapy, and it can cause side effects, including inflammation and autoimmune reactions. It is important for patients to work closely with their healthcare team to determine if immunotherapy is an appropriate treatment option for their individual case.

Why is cancer increasing these days? And How can I prevent it?

The incidence of cancer has been increasing over the years for a number of reasons, including aging populations, increased exposure to risk factors, and improved cancer detection methods.

Aging is a major risk factor for cancer because as people age, their cells accumulate genetic damage that can lead to the development of cancer. Additionally, many environmental and lifestyle factors can increase the risk of developing cancer, including smoking, exposure to radiation, unhealthy diet, physical inactivity, and exposure to certain chemicals.

To prevent cancer, there are several things you can do:

Quit smoking: Smoking is the leading cause of preventable cancer deaths worldwide. By quitting smoking, you can significantly reduce your risk of developing cancer.

Eat a healthy diet: A diet rich in fruits, vegetables, whole grains, and lean protein can help reduce the risk of developing cancer. Avoid processed and red meats, and limit your intake of alcohol.

Exercise regularly: Regular exercise can reduce the risk of developing cancer by helping to maintain a healthy weight and reducing inflammation in the body.

Protect yourself from the sun: Sun exposure can increase the risk of developing skin cancer. Use sunscreen with a high SPF and wear protective clothing when spending time in the sun.

Get screened for cancer: Screening tests can detect cancer early, when it is most treatable. Talk to your doctor about the appropriate screening tests for you based on your age, sex, and family history.

It is important to note that not all cancers can be prevented, but taking steps to reduce your risk can help lower your chances of developing the disease.

Back Pain & Lung Cancer: What's The Association With Them?

Back pain is a common symptom of many conditions, including lung cancer. Lung cancer is a type of cancer that starts in the lungs and can spread to other parts of the body. The association between back pain and lung cancer is that back pain is often a symptom of advanced lung cancer. As the cancer grows, it can press on the spine and cause pain in the back. However, it is important to note that back pain can also be caused by a variety of other conditions such as muscle strain, arthritis, and even just poor posture. Therefore, back pain alone is not a definitive indicator of lung cancer. If you are experiencing back pain and are concerned about lung cancer, it is important to see a doctor for a proper diagnosis and evaluation. A combination of imaging, blood test and biopsy may be needed to make a definitive diagnosis of lung cancer.

What are the advantages of stereotactic radiosurgery?

Stereotactic radiosurgery (SRS) is a non-surgical radiation therapy used to treat functional abnormalities and small tumors of the brain. It is one of the latest developments in radiosurgery that effectively kills malignant cells without damaging nearby healthy tissues. It is directed towards cancerous cells, so there is less chance of damage to normal healthy cells. It involves delivering a high dose of focused radiation therapy to a small, well-defined area in the brain or any other head part.

Stereotactic radiosurgery treats secondary cancers that have spread to the brain.

It is a minimally invasive technique that doesn't require any cut or incision.

It preserves healthy tissues as it can deliver precisely targeted radiation in fewer high-dose treatments than traditional therapy.

SRS is also used to treat some non-cancer or tumor conditions such as arteriovenous malformations (abnormal connection of veins and arteries) and complex cases of trigeminal neuralgia.

SRS can be used to destroy cancerous cells that are difficult to reach.

It is a pain-free procedure.
