Prostate cancer is a cancerous tumor in a man s prostate gland, a small gland that is responsible for producing the seminal fluid which transports and nourishes the sperm. It is a very common type of cancer among men. A few cases of prostate cancer tend to develop slowly while others may progress very fast.
Symptoms-
In the initial stages, prostate cancer may not show any symptom. However, in the latter stages, there may be symptoms such as:
Pain in the bones.
Erectile dysfunction.
Urination can get troublesome.
Presence of blood in the semen.
Pain and discomfort in the pelvic region.
Causes-
The exact causes of prostate cancer are not known. It starts to develop when certain cells in the prostate gland start to mutate. These mutations cause these cells to multiply at a very fast rate and thus, soon form tumors. Although the causes are not known, certain factors tend to aggravate this condition; them being:
Color: According to certain medical reports, a darker skin may mean increased chances of suffering from prostate cancer.
Age: The risk of developing prostate cancer tends to increase with age.
Genetics and Family History: Faulty genes could be another cause of this condition. Also, having some member in the family who is diagnosed with this type of cancer only increases the risks of you suffering from them.
Obesity: If you are obese, then you are more likely to develop prostate cancer.
Treatments-
The treatments for prostate cancer include:
Radiation Therapy: In this procedure, high energy rays are used to target and destroy cancer cells. Usually X-rays or protons are used to treat the cancer cells.
Hormone Therapy: Hormone therapy is a type of treatment wherein certain medications are administered to prevent your body from producing testosterone.
Surgery: If the other treatment methods do not produce desired results, then a surgery is carried out for the removal of the prostate gland. In addition to the prostate gland, some adjoining lymph nodes and tissues are also removed.
Chemotherapy: Chemotherapy is method of destroying cancer cells by injecting chemicals into the body. The medicines are injected into the veins in the arms. 

All About Prostate Cancer

What menstrual problems are to women, prostate problems are to men. The prostate is a gland in the lower abdomen that aids in the production of semen. The prostate is walnut sized in a young man, but can get enlarged with age. As it grows bigger, it can cause a number of problems. These are commonly seen after a man celebrates his 50th birthday.

There are three common prostate problems faced by men. Some of the symptoms that can tell if a man has a prostate problem are:

1. Difficulty faced while urinating
2. The urge to urinate frequently at night
3. Constant feeling of a full bladder
4. Pain while urinating
5. Blood in the urine

Prostatitis

This can be defined as inflammation of the prostate gland. In most cases the cause of this inflammation is unknown. However, there are two types of prostatitis; bacterial and nonbacterial. While the former reacts well to antibiotics, the latter is more difficult to control. Symptoms of this disease vary from one person to the next. Some of the factors that could trigger this disease are:

1. Chemical irritants
2. Past bacterial infection
3. Dysfunctional pelvic floor muscles
4. Sexual abuse
5. Chronic anxiety

Enlarged prostate

As mentioned earlier, as men get older, the prostate gland tends to grow in size. This growth is benign, but can block the bladder neck and prostatic urethra. This can cause problems urinating and lead to acute urinary retention. This can be very painful. Inserting a catheter can provide temporary relief and help release stored urine. Chronic retention is much less common and is associated with high bladder pressure and can damage the kidneys.

Prostate cancer

Advancing age and family genetic history are said to be the main triggers of prostate cancer. This type of cancer can remain restricted to the prostate gland in its early stages but may spread to the other glands as the cancer advances. This can also cause the growth of secondary tumors in the bones.

The only way to correctly diagnose a prostate problem is with a thorough physical examination. This includes a digital rectal exam where the doctor will insert a gloved finger into your rectum to check the size of your prostate, a blood test, mid stream urine tests and ultrasounds. In some cases a biopsy of the prostate may also be required. Depending on the diagnosis, your doctor may prescribe antibiotics, surgery, radiotherapy or hormone therapy to manage your prostate.

Are You at Risk of a Prostate Disease?

In recent years, there has been the emerging trend of resorting to customized treatment for different types of cancer. These treatments vary from individual to individual, depending on the severity of their condition. PSMA PET scan and DOTA scan are two such procedures used in the treatment of prostate cancer.

Before identifying the benefits of these scans, let us have a look at the risks of prostate cancer.

Prostate Cancer- What is it?

Prostate cancer shows up in the prostate gland of men, which produces the fluid that transfers and nourishes the sperm. It is a very commonly occurring condition in men and early treatment can cure it completely.

Symptoms of Prostate Cancer:

Prostate cancer starts showing its symptoms from the middle stages. One should seek medical help if he observes the following warning signs-

  Pain while urinating
  Bone pain
  Reduction in force of urine
  Erectile Dysfunction
  Presence of blood in semen

With increasing age and obesity, there remains a high chance of developing prostate cancer.

What is PSMA PET scan?

It is an effective and reliable mode of diagnosis to identify the extent of prostate cancer. It is also known as Prostascint scan. This scan is recommended for patients in the early stage of cancer and to determine whether the disease has spread to the pelvic lymph nodes.

In this process, the patient is injected with an antibody and a radioactive material that can be detected by cameras. The doctor then sees a three-dimensional picture of the affected area on the monitor. The complete process takes three days to finish.

Benefits of PSMA PET scan:

  Helps to determine the position and range of a tumour
  Helps the doctor to plan effective methods of treatment to eradicate a tumour completely
  Helps to predict the result of treatment up to a certain extent, unlike other imaging tests

What is DOTA scan?

It is a highly advanced scan used to detect the spread and sensitivity of tumours concerning prostate cancer. The molecules injected during the scan attaches itself to the neuroendocrine tumours known as carcinoids.

Benefits of DOTA scan:

  Helps to detect the exact location of a tumour
  Helps the doctor to plan for effective radioactive therapies
  Helps to identify the exact stage of a cancerous tumour

Both PSMA and DOTA scans are the fruits of modern scientific research and go a long way in eradicating cancerous cells from the body. Early detection of the disease with these scans increases the chance of being cured of the disease.

Prostate Cancer - Knowing The Importance Of PSMA PET Scan & Dota Scan!

One of the most common issues with old age in men is the enlarged prostate. Any difficulty with urination (no constant stream, difficulty initiating, or incomplete emptying of the bladder for instance), and the first suspect is an enlarged prostate. These symptoms are followed by a digital rectal exam to check for an enlarged prostate. Once confirmed, the next step is to check for levels of prostate-specific antigen (PSA). If both the exam and the PSA are positive, it could mean prostate cancer. As with any cancer, it is believed that sooner it is diagnosed and the treatment is started, the better.

Historically, the best way to rule out the prostate cancer had been to do a prostate biopsy. This is a minor invasive procedure, wherein biopsies are taken from various regions of the prostate which are known to develop cancer (about 12). A disadvantage of this procedure includes missing out on the front part of the prostate which can also develop cancer. Secondly, it is not a very pleasant experience and given a chance, most men would not want to have it done.

There is good news for these men who would like to avoid prostate biopsies. The first is the multiparametric MRI which uses no x-rays and is considered very safe with extremely accurate results. This MRI exam requires about an hour, and once the images are obtained, the doctor will analyse these images and check for several parameters to assess for prostate cancer. The absence of cancer can be confirmed with up to 90% accuracy, which is far greater than with usual biopsies. If there is a possibility of cancer, then a biopsy can be done to confirm it. 

Also, these images indicate the exact region where cancer likely is, and this guides the doctor to biopsy only where absolutely essential. The chances of false positive and false negative results are reduced drastically. The one disadvantage here is that MRI detected biopsies usually tend to be of a higher grade which requires immediate treatment.

Another way to reduce chances of the biopsy by 30% to 50% is by the 4K test. It helps detect a variety of prostate issues including cancer. It can be used once higher levels of PSA is identified and before going for a biopsy. It combined 4 prostate-specific biomarkers with clinical information to accurately provide men with a risk of developing prostate cancer. It can be used even after negative biopsies to confirm the diagnosis of prostate cancer.

These two measures can drastically reduce the incidence of prostate biopsies, which is neither pleasant for the patient nor very effective for the doctor.

Prostate Biopsies - Ways You Can Avoid It!

Prostate cancer is one of the most common cancers that men are diagnosed with. It is accompanied by a number of difficulties of urination and ejaculation. It can also cause difficulty in achieving and sustaining an erection. If cancer advances and affects the bone structure and the spine, it can cause weakness in the limbs, and also result in urinary and fecal incontinence. If it is diagnosed in its early stages it can be treated quite easily before it spreads.

Treatment for Prostate Cancer-
Prostate cancer generally does not show any symptom in the early stage but progressively degenerates with time. If you suspect having any of the symptoms of prostate cancer such as urination difficulty, erectile dysfunction and discomfort in the pelvic region, then consulting an oncologist is the next step. Your doctor will perform certain diagnostic tests like digital rectal examination (DRE) and prostate-specific antigen (PSA) test. After the diagnosis of prostate cancer, doctors generally check the stage and rate of growth of a tumour by determining its Gleason score.



Once the extent of the prostate cancer is known, a treatment plan is devised by the doctor. If the cancer is localised and small, your doctor will either prescribe active surveillance or surgery. During active surveillance, there is a blood test, rectal examination, and biopsies on a regular basis to monitor the growth of a tumour. However, the tumour can also be deftly removed with surgical intervention in the form of Radical Prostatectomy. There are two types of radical prostatectomy- laparoscopic prostatectomy and robotic laparoscopic prostatectomy

Robotic Radical Prostatectomy-
A radical prostatectomy is one of the most common methods of treating prostate cancer. It involves the surgical removal of the prostate gland along with some of the surrounding tissues. This curtails the spreading of the cancerous cells to other parts of the body. A robotic radical prostatectomy is a minimally invasive procedure that involves the use of a robotic instrument that is controlled by surgeons to make the removal of the gland precise and efficient. The surgeon controls the robot by sitting at a console and makes several small incisions to enter the abdomen. This procedure reduces the risks of blood loss and any possible side-effect that includes erectile dysfunction and urinary difficulties.

Robotic Radical Prostatectomy For Cancer Prostate!

The prostate is a vital organ that located between the penis and the bladder. The prostate is involved in the release of the prostate fluid that keeps the sperm properly nourished. Prostate cancer, as the term indicates, is characterized by the abnormal and uncontrolled growth of cancerous cells in the prostate. Though the incidences of prostate cancer are low in India, necessary precautions and diagnostic steps should be carried out to prevent the condition from jeopardizing our lives.

Prostate screening includes two tests known as the Digital Rectal Exam (DRE) and Prostate-Specific Antigen test (PSA). PSA combined with DRE helps to identify prostate cancer at a very early stage. If any of the tests show an abnormality, a doctor might prescribe an ultrasound such as MRI Fusion or Prostate Biopsy to confirm the diagnosis.

Immediate treatment may not be necessary
For low-risk prostate cancer, doctors often recommend active surveillance that includes periodic blood tests, rectal exam, and biopsies.
Active surveillance helps a doctor to continuously track the growth of cancer cells and the possibility of their spread to other areas of the body.
Surveillance is fit for those who are already suffering from a serious condition or for those patients who are above the age of 60.
A surgical procedure to remove prostate cancer
Surgery is considered when the cancer has metastasized to surrounding tissue and the lymph nodes. There are two kinds of surgeries that a patient can go through- a Robot-Assisted surgery and a Retropubic surgery.
Radical Prostatectomy might have risks involved. It is, therefore, wise to discuss the pros and cons of the surgery with the doctor well in advance.
Understanding the treatment options

Radiation therapy: Radiation therapy involves the use of high-powered and high-frequency energy beams to kill cancer cells. Radiation therapy is often used to shrink the size of the cancer cells. There could be two types of radiation therapy-Brachytherapy and External beam radiation. Radiation therapy too can have its side effects. Doctors prescribe several medicines during therapy.
Hormone therapy: Hormone therapy helps to stop the production of a male hormone known as testosterone. This treatment option includes medication that completely stops the production of testosterone, the medications may also block the flow of testosterone on the cancer cells, and surgery to remove the testicles. Hormone therapy is used in advanced cancer stages.
Chemotherapy: Chemotherapy is a drug that goes into the body and kills rapidly growing and metastasizing cancer cells. It is administered through IV (intravenous), or orally as pill or both. This treatment option is employed when cancer spreads to a remote body location and does not respond to hormone therapy.
Biological therapy: Biological therapy involves the usage of the body s immune system to fight cancer. A type of biological therapy known as the sipuleucel-t is used to treat patients with advanced cancer stage and recurring cancer as well.
