Breast Cancer - Treatment Procedures At Different Stages!

Breast Cancer - Treatment Procedures At Different Stages!

Breast Cancer can be detected at various stages. Some women might feel a difference in their breast area, with a lump or kind of a skin rash around the nipple or they could see that their nipple has become inverted, so then the treatment procedures would be different. The different stages of cancer and their respective treatment procedures are discussed below:

Stage I Breast Cancer - Treatment
In this case, breast cancers are at their nascent stage, either they have not spread to the lymph nodes or might have spread to only a small area. Treatment options are as follows:

  • Surgery: The main treatment for breast cancer in stage I is surgery. These types of cancers get treatment with either breast-conserving surgery or mastectomy. There are some cases when breast reconstruction can also be done along with the surgery to get rid of cancer.
  • Radiation therapy: When doctors feel the need to do a breast construction surgery, then radiation therapy is normally given after surgery. This helps in lowering the chance of cancer getting relapsed. Older women, aged close to 70 years, should go for breast reconstruction surgery without radiation therapy, provided the following conditions are true:
    • The lump was 2cm or less across and it has been completely removed.
    • None of the lymph nodes removed contained cancer.
    • The cancer is either ER or PR-positive and hormone therapy is conducted.
  • Chemotherapy and other drugs: Women who have either ER or PR-positive hormone receptor, doctors would recommend them to go for hormone therapy. The therapy is given for 5 years. In case the tumor is larger than 1cm across, adjuvant chemotherapy is recommended.

Stage II Breast Cancer-Treatment
This is the stage when cancer has spread to some nearby lymph nodes. The treatment methods followed are:

  • Surgery and radiation therapy: This second stage of cancer gets treated with breast-conserving surgery or mastectomy. The lymph nodes nearby get checked either with a sentinel lymph node biopsy or an axillary lymph node dissection. Women, on whom BCS have been conducted, get treated with radiation therapy after surgery.
  • Neoadjuvant and adjuvant systemic therapy: This is another method followed for treating stage II cancer. It is a good option for women with large tumors as they shrink the tumor before conducting surgery. Chemotherapy, HER2 targeted drugs and Hormone therapy all form part of treatment in this stage II.

Stage III Breast Cancer – Treatment
In stage III breast cancer, the size of a tumor is more than 5 cm, with cancer spreading on to the nearby lymph nodes. The treatment procedures followed are:

  • Neoadjuvant therapy: Generally the stage III cancers are treated with neoadjuvant chemotherapy. Radiation therapy is also given after surgery, followed by breast reconstruction surgery.
  • Starting off with surgery: Another treatment option for this stage is to get started off with surgery. The tumors are quite large and they even grow on to nearby tissues, which means women need to get a mastectomy. Women having large breasts can even go for Breast Reconstruction Surgery, in case cancer has not spread on to the nearby tissues.

In case you have a concern or query you can always consult an expert & get answers to your questions!

I have problem of sleep disc, and sometimes its agony what are the exercise for this?
Slip disc is a serious problem and can become debilitating too. Ayurveda has panchakarma to maintain such serious conditions. It can reduce the pain as well as its recurrence. Kindly consult some panchakarma consultant for best treatment. And consult yoga expert for exercises. Good luck.

Around 4 months back I was suffering from slight right hip pain for which sometimes I took tab. Voveran which improved the symptoms. After one month while standing suddenly I felt moderate pain in my lower back, I somehow managed to get along with it but I could not walk properly & felt great difficulty. I took Inj. Voveran BD for 5 days at home but finally on day 5 my symptoms worsened with immense pain in right hip. I visited hospital minute was given Inj. Myoril, Inj. Tramadol, Inj. Voveran and advised MRI. Next day my MRI revealed L3-S1 diffuse disc bulge, dessication, Small Annular Tear & right slight cord compression. My blood reports revealed severe Vit D and B12 deficiency. After taking almost 2 months strict bed rest, Vit. D/B12 supplements, Inj. PiroxicamX5, Inj. DepomedrolX2, Tab Feldex OD, Tab.LyricaTDS and Tab. MyospazTDS my symptoms got almost normal and finally I was able to walk but I still have mild lumbar discomfort & weakness in right leg. Now should I go for SXR or CST?

Hello, From the very precise history what you have given you have been diagnosed with intervertebral disc prolapse with cord compression. Now this is like a mechanical block obstructing the spinal cord (or nerve root), which cannot be removed or decreased with only medicines. The meds what you have taken help reduce the nerve irritation and the nerve swelling caused due to disc prolapse that's the reason why your symptoms have reduced. Every time there is stress on the back, your symptoms will reappear again because the prolapsed disc is still persists. Surgery is adviced depending on how much of a cord compression is there and your symptoms. If the compression is not severe, then life style modification is adviced. Reducing your weight also helps for your height of 182 cm your about 20 kg over weight. Back strengthening exercises will help. I would be in a better position to advise if I could see the MRI SCAN.

My MRI report says, Mild posterior broad base protrusion of L4-L5 intervertebral disc resultant mild central and lateral canal narrowing causing mild compression over thecal sac and right traversing L5 nerve root. I am doing bed rest from 10 days, what's the report says.

the report says that you have a disc prolapse and the disc is compressing one of the right nerve root. So if you have back and right leg pain then it would fit with your MRI findings. Absolute bed rest is not required for disc prolapse. as it is a mild prolapse there is a chance that the symptoms will improve with medications. avoid lifting heavy weight and reduce your body weight too

Herniated Disc - Know How It Affects You!

Herniated Disc - Know How It Affects You!

A herniated disc also known as a slip disc or prolapsed disc refers to the problem where one of the discs located in between the bones of the vertebrae(backbone) gets damaged and stacks itself upon the nerves. The tender inner portion of the disc gets protruded over the outer ring. Herniated disc causes severe neck pain and back pain. It occurs when the outer ring gets weak and tears down. The most common symptoms include pain and numbness, especially on one side of the body. The pain extends down to the arms and legs. It worsens during nighttime. The muscles become weak. Overweight people are likely to have this disease, as the discs carry extra weight. Old people are vulnerable to a slip disc.

Effects of Herinated Disc:

  • An untreated case of herniated disc may cause permanent damage to the nerves.
  • In certain cases, a herniated disc is capable of cutting off nerve impulses to the "caudal equine"nerves, present in the lower back and legs. This leads to loss of bladder control or bowel control.
  • Saddle anaesthesia is another long-term effect. Nerves are compressed by the slip disc, causing loss of sensation in the inner portions of your thighs, the back of your legs and surrounding the rectum region.
  • Symptoms may improve or worsen.

Diagnosis of Herinated Disc:

Treatment or diagnosis of herniated disc or slip disc can be either conservative or surgical in nature. The nature of treatment is determined according to your discomfort level and the kind of pain you are experiencing, or how much the disc has slipped out.

  • The pain caused by herniated disc can be relieved by undertaking an exercise schedule which includes stretching and strengthening the spine and its surrounding muscles.
  • A physiotherapist should be appointed for recommending the types of exercises.
  • Taking pain relievers also soothes the pain.
  • Stronger medicines prescribed by doctors include-muscle relaxers, narcotics to deal with the pain, medicines for nerve pain such as "gabapentin"  or "duloxetine".

In case of the symptoms not subsiding within a span of six weeks, a surgery may be recommended by your doctor. The surgeon may have to remove the damaged part of the disc. This surgery is called a microdiskectomy. In case you have a concern or query you can always consult an expert & get answers to your questions!

Stages Of Kidney Cancer - How They Can Be Managed?

Stages Of Kidney Cancer - How They Can Be Managed?

Kidney cancer or renal cancer is when kidney cells grow uncontrollably and form a tumour. Kidney cancer often begins in the tubules (tiny tubes in the kidneys). The prognosis may depend on the stage of the kidney cancer.

Different Stages of Kidney Cancer
The TNM system helps to categorize each stage of the kidney cancer.
Tumour (T) – Describes the size and location of the tumour.
Node (N) – Describes the spread of cancer to lymph nodes.
Metastatis (M) – Describes the spread of cancer to other body parts.

These results combined with the five stages (0 and 1 to 4) can help to identify the right treatment option for every patient. Zero stage describes no cancer presence. For instance –
Stage 1 – Here the tumour is confined to kidneys and its size is smaller than 7 centimetres. (T1 or T1, N0, M0)
Stage 2 – Here the tumour is confined to kidneys and its size is more than 7 centimetres. (T2)
Stage 3 – Here the tumour is in kidneys or blood vessels or fatty tissues but also a lymph node; cancer spreads to major veins but doesn’t extend beyond renal or Gerota’s fascia (connective tissues surrounding adrenal glands and kidneys). (T3)
Stage 4 – Here the cancer is in the fatty tissues surrounding kidneys and adjacent lymph nodes; has spread to other nearby organs and beyond renal fascia. (T4)

Treatment and management of kidney cancer
Once your doctor has determined the staging of your kidney cancer, a treatment plan can be formulated for you.

  1. Surgery
    • Simple nephrectomy removes the affected kidney.
    • Radical nephrectomy is a common surgery for kidney cancer. It removes all affected parts such as the kidneys, adrenal gland, lymph nodes and surrounding tissues.
    • Partial nephrectomy is for small tumours and removes the kidneys and the surrounding tissues.
  2. Interventional radiology: This is a surgery aided by real-time images. An advanced surgery using a nano knife is minimally-invasive and is effective for inoperable kidney tumours.
  3. Targeted therapy: Drugs target specific tumour cells and destroy them.
  4. Immunotherapy: Used for kidney cancer that has spread to other organs, this therapy may use different types of drugs to either help immune cells find cancer growth or regulate the immune system activity to stop or slow cancer growth.
  5. Arterial embolization: It is a procedure to stop blood supply to the kidney tumour, in order to shrink it in size prior to surgery.
  6. Cryotherapy: This procedure involves using extreme cold to kill cancer cells.

Chemotherapy is not very effective for treating kidney cancer. Talk to your doctor about all possible treatment options for your cancer. You can lower your risk of kidney cancer by eating healthy, maintaining your ideal body weight and managing your blood pressure. In case you have a concern or query you can always consult an expert & get answers to your questions!

I am having slip disc. I want to know to cure it with exercises and what are the precautions to took for this?

Till you have pain, exercises would have little help. Initially you have to take bed rest. Avoid forward bending & cross-legged sitting on ground. Sit with a straight back. You can wear l. S. Belt temporarily. When pain subsides you can start exercises as guided by your doctor to prevent future disc problems.

Breast Cancer - The Truth !

MBBS, DNB ( Radiation Oncology)
Oncologist, Mumbai

Breast Cancer is the most common cancer of females in urban cities. It is a curable disease if detected early. The usual age of presentation is usually after 40 to 50 years of age, though it is becoming common in earlier age as well. This could be due to many factors like late marriages, older age of pregnancy, diet and lifestyle, etc. The usual presentation is a swelling or lump in the breast, not associated with pain. That is the reason why females are advised regular self-breast examination, clinical breast examination and annual mammograms for screening purpose in order to detect early breast cancers. Many times, the breast lump is associated with blood stained discharge from the nipple. There can be skin changes on the breast like thickening, crusting or sometimes itching. If the skin lymphatics get blocked, there may be pitting and or dimpling of the skin too. There may be lumps felt in the armpit felt too. Many times the lump is not noticeable or felt and felt by chance during a bath. These are some of the commonest presentations. The lady should immediately consult a doctor and get evaluated in such scenario. Many women are at increased risk of developing breast cancer like those who have a positive family history especially first degree relatives like mother& sister. Breast cancer is usually a disease of women but 1% of cases are also seen in men.

If a lady feels any such lump she should immediately bring it to the attention of a doctor or oncologist who can do the necessary evaluation and investigations. Breast cancer is curable if detected early, hence the importance!

The primary modality of treatment is surgery followed by chemotherapy and or radiotherapy and or hormonal treatment depending on the report of the specimen after the surgery. Many times if the lump cannot be operated upfront, initially chemotherapy and or targeted therapy can be given to shrink the tumor for better resectability.

People should be aware that having cancer is not the end of life. It can be treated like many other diseases and the most important thing is awareness and early detection for a durable cure.

What You Need To Know About Breast Cancer Surgery?

With the recent number of breast cancer cases on the rise, it is important that we should get the examination done on a regular basis as a preventive measure. Even if someone is suffering from it, it is important that we should make an effort and learn about.

If you have breast cancer then a surgery will be part of your treatment. Based on the condition, surgery will be carried out due to any of the following reasons:
1. To remove the cancerous tissues from the breast
2. To reconstruct the breast once the cancer is removed
3. To check whether the cancer has spread to the lymph nodes below the arm
4. To treat symptoms of cancer that has progressed to an advanced stage

Breast cancer surgery may be classified into two types
1. Mastectomy: Mastectomy involves removing the entire breast; tissues in the adjoining region may also be removed. A double mastectomy is a procedure where both the breasts are removed.
2. Breast-conserving surgery: In this surgery, only parts of the breast affected by cancer are removed. The area of the breast that is to be removed will depend on the severity of the cancer. Some healthy tissues may also be removed in this surgery.

Usually, if a woman is in the initial stages of cancer then she may opt for the latter as it entails removing parts of the breast. They may also undergo radiation therapy along with these surgeries.
For checking if the cancer has spread to the lymph nodes below the arm, the lymph nodes are removed from the body. Once they are removed, they are studied under a microscope to check if it has spread, if yes then the extent of their damage. This procedure is carried out along with the surgery to remove the cancer.

Once the mastectomy procedure is completed, you can opt for a breast reconstruction surgery to rebuild the area. You may opt for this procedure at the time of breast cancer removal or at a later stage. If you are considering breast reconstruction surgery then you should discuss it with your surgeon.

Surgery is sometimes not used to treat cancer, but in slowing the progression of cancer or even reducing its symptoms.It is important you talk to your surgeon before the procedure to understand the goal of the surgery.

In case you have a concern or query you can always consult an expert & get answers to your questions!

Everything You Need to Know About Your Pap Smear!

MD - General Medicine, MBBS

Everything You Need to Know About Your Pap Smear!

A Pap Smear is a screening test done to to test for occurrence of uterine cancer. Carried out in a quick and simple way to extract a sample, the sample is collected from the cervix area of a woman during a pelvic exam. The examination of the sample takes place under a microscope thereafter to find abnormalities that can point towards cancer and pre cancer changes.

There are many reasons why women should get a pap smear screening done:

1. Women who are HIV positive should get this test done regularly so as to detect any anomalies in the cervix. This condition usually comes with higher risk of infections and cancer, which is why regular screening is required.

2. Age is also another factor and women over the age of 30 should go through an annual screening on a compulsory basis. This is also true for women who have been through pregnancy and child birth.

Preparing for a Pap Smear: To prepare for a pap smear test, you need to ensure that you are not menstruating at the time. Also, you may want to avoid sexual activity just before the test so as to get the most accurate readings. During the process, remember to stay calm and relax your body physically.

Procedure: The pap smear procedure is a quick one that might be only slightly uncomfortable. This test is usually carried out on the examination table at the gynecologist's clinic. The legs will need to be spread and placed in stirrups. The doctor will insert a speculum to hold open the vaginal opening so that the spatula can be inserted easily to take a sample from the area. This sample of the cells will be tested in a lab after due preservation.

Test Results: The test results can either be normal or abnormal. An abnormal result does not point at the presence of cancer. Rather it can simply mean that abnormal cells exist in the cervix. The doctor may ask you to go through these tests and screening more frequently so as to study the anomalies in a more detailed manner. Consult an expert & get answers to your questions!
