What is Cancer and Prostate Cancer?
Aside from a fearsome word, cancer in general and prostate cancer in particular is a group of diseases characterized by uncontrolled growth and spread of abnormal cells, with unknown causes (although many are assumed) and which sounds to many like a death sentence.
Prostate cancer begins when cells in a man’s prostate gland grow out of control and take over healthy cells. It is a slow-growing malignant growth…»»Read more: Prostate Cancer: Symptoms, Treatments, Data
Joseph C. Presti Jr. says in “Prostate Cancer: Principles and Practice” (page 23):

“…needle biopsy of the prostate represents a sampling of the gland, and accurate prediction of tumor grade within the prostate may be hindered by sampling error. In general, in several series correlating tumor grade on the biopsy with the grade of tumor in the radical prostatectomy specimen, needle biopsies exactly correlate with the prostatectomy in 31% to 59% of…
This is quite a subjective topic. Some people (most people) only feel a slight sting, while others accuse very bad consequences (such as prostatitis) following prostate biopsy. Just like someone may cry when gets stinged by a needle, while others will look at the the sting and feel ok.
But one thing is certain: when the needle is inserted, you will feel a sharp pain in the prostate. Calm down, take…»»Read more: Prostate Biopsy- How does it feel?
The prostate biopsy is an important part of the diagnosis process of cancer, and this is because an accurate and early estimation of tumor grade significantly helps prostate cancer patients in their management of prostate disorders.
There are many kinds of biopsies: lung, breast, liver etc. and of course, prostate biopsies.
The etimology of this word sais it all: Biopsy= bios (greek- life) + opsis (greek- view).
So it’s a “slice” of a living organ[ism] which…»»Read more: The Prostate Biopsy
Here are some statistics on prostate cancer, relative to the year 2007:
- 559.650 Americans are expected to die of all forms of cancer, cancer being exceeded in the US only by heart diseases. Survival rates have improved in the last decade, being now to about 66% (1996-2002), and growing from a 55% between 1975-1977. This increase reflects the higher early-stage rate in cancer diagnosis and the better prostate cancer treatments options…
The First Cell
The body is made up of cells, organs and tissues. But here is the magic part: all of these different cells are derived from the single cell that resulted from the fertilized egg. So, as the embryo grows, the cells multiply and change, or differentiate, into whatever cell type is the basic brick/building block of a particular tissue or organ. The initial cells are what is called embryonic…»»Read more: Prostate Cancer Staging (Cells, Differentiation, Gleason Score)
Digital Rectal Exam & Prostate Biopsy
In more recent studies, only 26% to 34% of men with suspicious findings on DRE have positive biopsies for cancer (1,2 and 3). So unfortunately the most widely used test for the detection of prostate cancer turns out to be the most subjective. Some factors affecting the results of DRE include: examiners’ skills, varied indication for the examination, selection of patients based on symptoms and age,…»»Read more: Digital Rectal Exam & Prostate Biopsy
DRE – How to perform a Digital Rectal Exam
The DRE remains a cornerstone in the diagnosis of prostate cancer, owing to its ease, lack of cost, low risk, and contribution to detection of cancer in men with normal PSA levels. With its low position in the pelvis, below the bladder neck, the anatomic position of the prostate allows palpation of the posterior wall by the finger placed per rectum. The…»»Read more: Digital Rectal Examination (DRE)- Prostate Rectal Exams
Digital Rectal Exams | PSA | Prostate Cancer
Because a part of the prostate gland can be felt through the rectum, an experienced doctor can do a digital rectal exam (DRE) and determine if there is any unusual growth or abnormality. A normal prostate is fairly soft and uniform. If there is prostate cancer present, depending on the stage and location, it may be hard (indurated) with lumps and nodules. If…»»Read more: DRE Digital Rectal Exams in detection of Prostate Cancer (PSA)
