On some systems, notably later versions of the Mac OS X, the system may not recognize the Certificate Authority that The Cancer Imaging Archive uses to protect content from the web site transmitted via the https protocol and to sign Java Web Start applications, such as the Download Managers. In these cases, Java may give a certificate warning, asking if you really trust this site enough to run the program. In all cases, newer versions of Java will also ask the user if they really want to launch a program that has access to their files. (Obviously, Download Manager needs such access in order to store downloaded files.) The user must answer in the affirmative (i.e. 'yes, I trust this site' or 'yes, I trust this program' in order for Download Manager to start. One can avoid the warnings by either putting the cancerimagingarchive.net into "exceptions" list (i.e. trusted sites list) on the security tab in Java's control panel (only available in later versions of Java 7), or lowering the Java security level temporarily to "Medium" (not recommended).

Do the exams in TCIA show both malignant and benign tumors?
All patients that who are part of TCIA at this time are cancer-positive by definition. We don’t have any no collections of non-malignant tumors or healthy patients, so in general the tumors would be malignant. The only exception could would be patients with multiple tumors who might have a benign tumor in addition to a malignant tumor, but at least one tumor should always will be malignant in each patient.
